Superconductivity makes physics seem like magic. At cold temperatures, superconducting materials allow electricity to flow indefinitely while expelling outside magnetic fields, causing them to levitate above magnets. MRIs, maglev trains, and high-energy particle accelerators use superconductivity, which also plays a crucial role in quantum computing, quantum sensors, and quantum measurement science. Someday, superconducting electric grids might deliver power with unprecedented efficiency.

Yet scientists lack full control over conventional superconductors. These solid materials often comprise multiple kinds of atoms in complicated structures that are difficult to manipulate in the lab. Its even harder to study what happens when theres a sudden change, such as a spike in temperature or pressure, that throws the superconductor out of equilibrium.

Quantum theory has predicted intriguing behaviors when a superconductor is driven out of equilibrium. However, it has been challenging to perturb these materials in the lab without disrupting their delicate superconducting properties, leaving these predictions untested.

However, scientists can obtain surprisingly deep insights into superconductivity by studying it with fully controllable arrays of atoms in a gas. That is the approach of a research collaboration at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder.

In their latest work, JILA researchers caused a gas of strontium atoms to act like a superconductor. Even though the strontium atoms themselves are not superconducting, they follow the same rules of quantum physics. The researchers could make atoms in a gas interact in a way that preserves the sorts of interactions responsible for superconductivity while suppressing other competing, complex interactions. By throwing the atoms out of equilibrium, the researchers saw changes in atomic interactions that would affect the properties of actual superconductors.

With their strontium gas acting as a quantum simulator, the researchers were able to observe a behavior of superconductors that has been predicted to exist for years. This study, published in Nature, offers new insight into how superconductors work when appropriately driven out of equilibrium, and sheds light on how to make superconductors more robust, and how to use their unique properties in other quantum technologies.

In a normal material, electrons move in an incoherent way, bumping into one another constantly; normally, electrons repel each other. As they move, they collide, losing energy and generating heat; thats why electric currents dissipate when electrons flow in a metallic wire. In a superconductor, however, electrons join up into weakly bonded pairs, called Cooper pairs. When these pairs form, they all tend to move coherently, and that is why they flow through the material with no resistance.

The physics is simple in some sense, explains theoretical physicist Ana Maria Rey, a NIST and JILA Fellow. Cooper pairs exist in a low-energy state because vibrations in the materials crystalline structure pull the electrons together. When formed, Cooper pairs prefer to act coherently and lock together. The Cooper pairs are kind of like arrows that want to line up in the same direction. To unlock them or make one of the arrows point along a different direction, you need to add extra energy to break the Cooper pairs, Rey explains. The energy that you need to add to unlock them is called an energy gap. Stronger interactions between the atoms create a larger energy gap because the attraction that keeps the Cooper pairs locked is so strong. Overcoming that energy gap takes a lot of energy away from the Cooper pairs. So this energy gap acts as a buffer, letting the Cooper pairs remain happily locked in phase.

This all works when the system is in equilibrium. But when you introduce a sudden, rapid change, the superconductor falls out of equilibrium, or becomes quenched. For decades, scientists have wanted to know what happens to superconductivity following a quench that is abrupt but not so strong to completely break the Cooper pairs, said JILA physicist James Thompson.

In other words, how robust are these things? Thompson said.

Theorists predicted three different possibilities or phases that could happen when the superconductor is quenched. Think of it like a big group of square dancers, Thompson says. At first everyone is in sync, keeping to the beat of the music. Then some people get a little tired or some others start moving a little too fast, they crash into each other, and it turns into a mosh pit. Thats Phase I, when superconductivity collapses. In Phase II, the dancers get off the beat, but manage to stay in sync. Superconductivity survives the quench. Scientists have been able to observe and study these two phases.

But they have never seen a long-predicted third phase, in which the superconductivity of the system oscillates over time. In this phase, our dancers will move a bit faster or a bit slower at times, but no one crashes. That means sometimes its a weaker superconductor, and sometimes its a stronger superconductor. Until now, no one had been able to observe that third phase.

Working with Reys theory group, Thompsons team at JILA laser-cooled and loaded strontium atoms into an optical cavity, a space with highly reflective mirrors at either end. Laser light bounces back and forth millions of times before some light leaks out at one end.

The light in the cavity mediated interactions between the atoms, causing them to align into a superposition state meaning they are in both the excited and ground state at the same time and to lock in phase, like Cooper pairs do, Rey explains.

Using lasers, scientists can quench the system, and by measuring the light that leaks out, they learn how the energy gap has changed over time. With this quantum superconductor simulation, they were able to observe all three dynamic phases for the first time.

They found that in the third phase the energy gap can keep superconductivity going even when the system is out of equilibrium. Using quantum simulators like this could help scientists engineer unconventional or more robust superconductors, and better understand the physics of superconductors in general.

Its also a counterintuitive way for scientists who work in measurement science to see atomic interactions, like the ones that cause the energy gap, as a benefit, not a curse.

In measurement science, interactions are usually bad. But here, when interactions are strong, they can help you. The gap protects the system everything flows, Rey says. At the heart of this idea you could have something that oscillates forever.

Having something that oscillates forever is a dream for quantum technology, Thompson adds, because it would let sensors work better for longer. Much like the superconductors, groups of atoms, photons and electrons in quantum sensors need stay in sync, or coherent, to work, and we dont want them to turn into a quantum mosh pit or dephase.

I am stoked that one of the dynamical phases that we observe can be used to protect quantum optical coherence against dephasing. For instance, this may one day allow an optical atomic clock to tick for longer, Thompson said. It represents a whole new way to increase the precision and sensitivity of quantum sensors, a topic that is at the frontier of quantum metrology, or measurement, science. We want to harness the many atoms and take advantage of the interactions to build a better sensor.

Physicists Just Measured Gravity on the Smallest Scale Ever By Using a Promising New Technique – Inverse

March 12, 2024 | Author: admin

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever.

In a clever tabletop experiment, researchers at Leiden University in the Netherlands, the University of Southampton in the UK, and the Institute for Photonics and Nanotechnologies in Italy measured a force of around 30 attonewtons on a particle with just under half a milligram of mass. An attonewton is a billionth of a billionth of a newton, the standard unit of force.

The researchers say the work could unlock more secrets about the universes very fabric and may be an important step toward the next big revolution in physics.

But why is that? Its not just the result: its the method and what it says about a path forward for a branch of science critics say may be trapped in a loop of rising costs and diminishing returns.

On smaller scales, the effects of gravity get weaker and weaker.

From a physicists point of view, gravity is an extremely weak force. This might seem like an odd thing to say. It doesnt feel weak when youre trying to get out of bed in the morning!

Still, compared with the other forces that we know about such as the electromagnetic force that is responsible for binding atoms together and for generating light and the strong nuclear force that binds the cores of atoms gravity exerts a relatively weak attraction between objects.

And on smaller scales, the effects of gravity get weaker and weaker.

Its easy to see the effects of gravity on objects the size of a star or planet, but it is much harder to detect gravitational effects for small, light objects.

We still dont understand how gravity, and thus black holes, work in the quantum realm.

Despite the difficulty, physicists really want to test gravity at small scales. This is because it could help resolve a century-old mystery in current physics.

Physics is dominated by two extremely successful theories.

The first is general relativity, which describes gravity and spacetime at large scales. The second is quantum mechanics, which is a theory of particles and fields the basic building blocks of matter at small scales.

These two theories are in some ways contradictory, and physicists dont understand what happens in situations where both should apply. One goal of modern physics is to combine general relativity and quantum mechanics into a theory of quantum gravity.

One example of a situation where quantum gravity is needed is to fully understand black holes. These are predicted by general relativity and we have observed huge ones in space but tiny black holes may also arise at the quantum scale.

At present, however, we dont know how to bring general relativity and quantum mechanics together to give an account of how gravity, and thus black holes, work in the quantum realm.

Until recently, scientists thought wed need equipment even bigger than the Large Hadron Collider to conduct these experiments.

A number of approaches to a potential theory of quantum gravity have been developed, including string theory, loop quantum gravity, and causal set theory.

However, these approaches are entirely theoretical. We currently dont have any way to test them via experiments.

To empirically test these theories, wed need a way to measure gravity at very small scales where quantum effects dominate.

Until recently, performing such tests was out of reach. It seemed we would need very large pieces of equipment, even bigger than the worlds largest particle accelerator, the Large Hadron Collider, which sends high-energy particles zooming around a 27-kilometer loop before smashing them together.

This is why the recent small-scale measurement of gravity is so important.

The experiment conducted jointly between the Netherlands and the UK is a tabletop experiment. It didnt require massive machinery.

The experiment works by floating a particle in a magnetic field and then swinging a weight past it to see how it wiggles in response.

This is analogous to the way one planet wiggles when it swings past another.

By levitating the particle with magnets, it can be isolated from many of the influences that make detecting weak gravitational influences so hard.

The beauty of tabletop experiments like this is they dont cost billions of dollars, which removes one of the main barriers to conducting small-scale gravity experiments, and potentially to making progress in physics. (The latest proposal for a bigger successor to the Large Hadron Collider would cost US$17 billion.)

Tabletop experiments are very promising, but there is still work to do.

The recent experiment comes close to the quantum domain, but doesnt quite get there. The masses and forces involved will need to be even smaller, to find out how gravity acts at this scale.

We also need to be prepared for the possibility that it may not be possible to push tabletop experiments this far.

There may yet be some technological limitation that prevents us from conducting experiments of gravity at quantum scales, pushing us back toward building bigger colliders.

Its also worth noting some of the theories of quantum gravity that might be tested using tabletop experiments are very radical.

Some theories, such as loop quantum gravity, suggest space and time may disappear at very small scales or high energies. If thats right, it may not be possible to carry out experiments at these scales.

After all, experiments as we know them are the kind of thing that happen at a particular place, across a particular interval of time. If theories like this are correct, we may need to rethink the very nature of experimentation so we can make sense of it in situations where space and time are absent.

On the other hand, the very fact we can perform straightforward experiments involving gravity at small scales may suggest that space and time are present after all.

Which will prove true? The best way to find out is to keep going with tabletop experiments, and to push them as far as they can go.

Design rules and synthesis of quantum memory candidates – EurekAlert

March 12, 2024 | Author: admin

In the quest to develop quantum computers and networks, there are many components that are fundamentally different than those used today. Like a modern computer, each of these components has different constraints. However, it is currently unclear what materials can be used to construct those components for the transmission and storage of quantum information.

In new research published in the Journal of the American Chemical Society, University of Illinois Urbana Champaign materials science & engineering professor Daniel Shoemaker and graduate student Zachary Riedel used density functional theory (DFT) calculations to identify possible europium (Eu) compounds to serve as a new quantum memory platform. They also synthesized one of the predicted compounds, a brand new, air stable material that is a strong candidate for use in quantum memory, a system for storing quantum states of photons or other entangled particles without destroying the information held by that particle.

The problem that we are trying to tackle here is finding a material that can store that quantum information for a long time. One way to do this is to use ions of rare earth metals, says Shoemaker.

Found at the very bottom of the periodic table, rare earth elements, such as europium, have shown promise for use in quantum information devices due to their unique atomic structures. Specifically, rare earth ions have many electrons densely clustered close to the nucleus of the atom. The excitation of these electrons, from the resting state, can live for a long timeseconds or possibly even hours, an eternity in the world of computing. Such long-lived states are crucial to avoid the loss of quantum information and position rare earth ions as strong candidates for qubits, the fundamental units of quantum information.

Normally in materials engineering, you can go to a database and find what known material should work for a particular application, Shoemaker explains. For example, people have worked for over 200 years to find proper lightweight, high strength materials for different vehicles. But in quantum information, we have only been working at this for a decade or two, so the population of materials is actually very small, and you quickly find yourself in unknown chemical territory.

Shoemaker and Riedel imposed a few rules in their search of possible new materials. First, they wanted to use the ionic configuration Eu3+ (as opposed to the other possible configuration, Eu2+) because it operates at the right optical wavelength. To be written optically, the materials should be transparent. Second, they wanted a material made of other elements that have only one stable isotope. Elements with more than one isotope yield a mixture of different nuclear masses that vibrate at slightly different frequencies, scrambling the information being stored. Third, they wanted a large separation between individual europium ions to limit unintended interactions. Without separation, the large clouds of europium electrons would act like a canopy of leaves in a forest, rather than well-spaced-out trees in a suburban neighborhood, where the rustling of leaves from one tree would gently interact with leaves from another.

With those rules in place, Riedel composed a DFT computational screening to predict which materials could form. Following this screening, Riedel was able to identify new Eu compound candidates, and further, he was able to synthesize the top suggestion from the list, the double perovskite halide Cs2NaEuF6. This new compound is air stable, which means it can be integrated with other components, a critical property in scalable quantum computing. DFT calculations also predicted several other possible compounds that have yet to be synthesized.

We have shown that there are a lot of unknown materials left to be made that are good candidates for quantum information storage, Shoemaker says. And we have shown that we can make them efficiently and predict which ones are going to be stable.

Daniel Shoemaker is also an affiliate of the Materials Research Laboratory (MRL) and the Illinois Quantum Information Science and Technology Center (IQUIST) at UIUC.

Zachary Riedel is currently a postdoctoral researcher at Los Alamos National Laboratory.

Quantum physics and the end of naturalism | Bruce L. Gordon – IAI

March 12, 2024 | Author: admin

Naturalism, the idea that there are no gods, spirits, or transcendent meanings, is the leading theory of our time. However, in this instalment of our idealism series, in partnership with the Essentia Foundation, Bruce Gordon argues that quantum mechanics not only beckons the end of naturalism, but also points towards the existence of a transcendent mind.

Naturalism remains a popular philosophy in the academic world. Its articulation varies, so lets be clear what we mean. Theoretical physicist and philosopher Sean Carrolls definition will suffice: Naturalism is a philosophy according to which there is only one worldthe natural world, which exhibits unbroken patterns (the laws of nature), and which we can learn about through hypothesis testing and observation. In particular, there is no supernatural worldno gods, no spirits, no transcendent meanings. Advocates of naturalism tend to regard it as the inevitable accompaniment of a scientific mindset. It seems appropriate, therefore, to undermine it using the most fundamental of sciences: quantum physics.

Given its scientific pretensions, its appropriate that the doctrine that the natural world is self-contained, self-explanatory, and exceptionless is at least falsifiable. All we need is one counterexample to the idea that nature is a closed system of causes and effects, or one clear example of natures non-self-sufficiency, to be justified in rejecting naturalism, yet contrary evidence and considerations abound. Rather than trying to cover the gamut of cosmological fine-tuning, the origin of biological information, the origin and nature of consciousness, and the evidentiary value of near-death experiences, lets focus on the implications of quantum physics as a less familiar aspect of naturalisms failure.

___

Particle talk has pragmatic utility in relation to measurement results and macroscopic appearances, but no basis in unobserved (mind-independent) reality.

___

Quantum physics sets aside classical conceptions of motion and the interaction of bodies and introduces acts of measurement and probabilities for observational outcomes in an irreducible way not ameliorated by appealing to our limited knowledge. The state of a quantum system is described by an abstract mathematical object called a wave function that only specifies the probability that various observables will have a particular value when measured. These probabilities cant all equal zero or one and measurement results are irreducibly probabilistic, so no sufficient physical reason exists for one outcome being observed rather than another. This absence of sufficient material causality in quantum physics has experimentally confirmed consequences that, as we shall see, put an end to naturalist conceits.

SUGGESTED READING Quantum mechanics makes no sense without the mind By Shan Gao

The delayed-choice quantum eraser experiment provides a good example with which to start. This experiment measures which path a particle took after wave function interference inconsistent with particle behavior has already been created. The interference can be turned off or on by choosing whether or not to measure which way the particle went after the interference already exists. Choosing to look erases wave function interference and gives the system a particle history. The fact that we can make a causally disconnected choice whether wave or particle phenomena manifest in a quantum system demonstrates that no measurement-independent causally-connected substantial material reality exists at the microphysical level.

We see this in other ways too. First, the physically reasonable assumptions that an individual particle, like an electron, cannot serve as an infinite source of energy or be in two places at once, entail that quantum particles have zero probability of existing in any bounded spatial region, no matter how large. Unobserved electrons (for example) dont exist anywhere in space, and thus have no reality apart from measurement. In short, there is no intelligible notion of microscopic material objects: particle talk has pragmatic utility in relation to measurement results and macroscopic appearances, but no basis in unobserved (mind-independent) reality.

Secondly, microphysical properties do not require a physical substrate. Reminiscent of Alice in Wonderland, quantum physics has its own Cheshire Cat in which quantum systems behave like their properties are spatially separated from their positions. For example, an experiment using a neutron interferometer has sent neutrons along one path while their spins follow another. In macroscopic terms, this would be like still having the spin once the top is taken away, having a dance without any dancer, or having a water wave without any water. Under appropriate experimental conditions, quantum systems are decomposable into disembodied propertiesa collection of Cheshire Cat grins.

___

While this quantum sea is the basis of our experiential reality, none of the mathematical-structural components of interacting quantum wave functions are materially real.

___

But how, then, should we understand the transition between the microscopic and macroscopic worlds? Every quantum wave function is expressible as a superposition of different possibilities (states) in which the thing it describes fails to possess the properties those possibilities specify. No quantum system, microscopic or macroscopic, ever has simultaneously determinate values for all its associated properties. You could think of it this way: imagine a house that, if you were looking at the front, didnt have a back, and vice-versa. Everything we experience with our senses, if we take it to be a mind-independent object rather than just a phenomenological appearance, is metaphysically incomplete. What is more, under special laboratory conditions, we can create macroscopic superpositions of properties that are, classically speaking, inconsistentfor instance, a single object appearing in more than one location simultaneously. Large organic molecules have been put into such superpositions, and Superconducting Quantum Interference Devices (SQUIDs) have superposed a billion electrons moving clockwise around a superconducting ring with another billion electrons moving anticlockwise, so that two incompatible macroscopic currents are in superposition.

What this reveals is that the macroscopic stability we normally observe is the product of what physicists call environmental decoherencethe destructive interference of probability waves as quantum systems interact. You can imagine this as two water waves the same size meeting each other from opposite directions. When the crest of one wave meets the trough of the other, there is destructive interference as the waves cancel out and waters surface is momentarily flat and calm. The quantum realm behaves analogously: our experiential world of appearances is cloaked in an illusory stability, while underneath, innumerable probability waves are destructively interfering in a roiling quantum sea.

SUGGESTED VIEWING Beyond Quantum With Gerard 't Hooft

It is important to keep in mind that, while this quantum sea is the basis of our experiential reality, none of the mathematical-structural components of interacting quantum wave functions are materially real. They are mathematical abstractions, a hollow and merely quantitative informational architecture. Speaking of the mathematical framework of physical theory, Robert Adams remarks that [it] is a framework that, by its very nature, needs to be filled in by something less purely formal. It can only be a structure of something of some not merely structural sort it participates in the incompleteness of abstractions [whereas] the reality of a substance must include something intrinsic and qualitative over and above any formal or structural features it may possess. Our experiential reality rests on a quantum-informational construct that is not materially substantial.

As a final observation before nailing the coffin of naturalism shut, in the case of laboratory-created macroscopic superpositions, our conscious self is not in the superposition but rather observing it. We are substantial, but the world of our experience is not. Our mental life transcends quantum reality. While this reality is given to us and not produced by our own consciousness, it is merely phenomenologicalit goes no deeper than the perceptual possibilities across all five of our sensory modalities decohering (destructively interfering) to produce our world.

But why should this be so? When there is no sufficient physical reason why one observation occurs rather than another, why should mere perceptions cohere across our sensory modalities, and why should all of us inhabit the same world? Saying that since no physical explanation is possible, no explanation is required, would be a mistake of disastrous proportions. If there were no reason why we observe one thing rather than another, if the regularities of nature were metaphysically ungrounded, then our current perception of reality and its accompanying memories might be happening for no reason at all. How could we know? No objective probability and hence no likelihood is assignable to something for which there is no explanation, so we couldnt even say this possibility is unlikely.

___

Clearly, naturalism is inadequate: it cannot meet the ineluctable explanatory demand. A proper ultimate explanation must terminate upon something that transcends contingent reality and has self-contained existence as its very essence.

___

Lets be perfectly clear. If we affirm brute chance by saying that some things can happen for no reason at all, we have deprived ourselves of any basis for deciding which things these are, and they could well include all of the perceptions and beliefs we currently take ourselves to have. This means we dont even know whether were in touch with reality. Were stuck with an irremediable skepticism that deprives our experience of any credibility, not only destroying any basis for doing science, but eliminating the very possibility of our knowing anything at all! Embracing brute chance by denying that every contingent event must have an explanation is the pathway to epistemic nihilism. An explanation must exist.

SUGGESTED READING Reality is not a simulation and why it matters By Marcelo Gleiser

But what could the explanation be? The laws of nature, specifically those of quantum physics, wont suffice. Theyre neither logically nor metaphysically necessary. The reality they describe did not need to exist and they certainly didnt cause its existencein short, they are in need of explanation themselves. Clearly, naturalism is inadequate: it cannot meet the ineluctable explanatory demand. A proper ultimate explanation must terminate upon something that transcends contingent reality and has self-contained existence as its very essence.

The required conclusion is obvious: since every contingent state of affairs requires an explanation, there must exist a transcendent, independent, necessarily existent being the existence of which is explained by its intrinsic necessity. This being is unique, not just because two or more necessary beings is overkill, but because their mutual dependence would create unexplainable contingency. Furthermore, since spacetime and mass-energy are contingent phenomena, this transcendent being must be incorporeal. Finally, in explaining why any reality exists, especially in the absence of a uniquely best reality, a non-arbitrary self-determined decision based on a perfectly ranked and complete set of reasons known to this necessarily existent being must be made. This means the necessary ground for the phenomenological reality of our experience is a transcendent, omniscient Mind. Given such considerations, quantum physics not only shows the falsity of naturalism, it leads to a transcendent form of idealism. Goodbye, Richard Dawkins, and hello, Bishop Berkeley!

Quantum computing and finance | UDaily – University of Delaware

Over the next decade, quantum computers are expected to have a transformative impact on numerous industry sectors, as they surpass the computational capabilities of classical computers. In finance, for example, quantum computing will one day be used to speed banking, make financial predictions and analyze financial patterns and risks.

The technology, however, is still in its infancy.

The University of Delawares Ilya Safro, associate professor and associate chair for graduate studies and research in the Department of Computer and Information Sciences, is part of a team of researchers from industry, academia and the U.S. Department of Energys Argonne National Laboratory that recently published a primer on quantum computing and finance.

The paper, published in Nature Reviews Physics, summarizes the current state of the art in quantum computing for financial applications and outlines advantages and limitations over classical computing techniques used by the financial industry. It also sheds light on some of the challenges that still need to be addressed for quantum computing to be used in this way.

It's an important topic across the world and at UD, which is among the first institutions in the United States to offer an interdisciplinary graduate degree program in quantum science and engineering.

The work, facilitated by the Chicago Quantum Exchange (CQE) and led by a team that includes UD, Argonne, JPMorgan Chase and University of Chicago scientists, lays groundwork for future applications and highlights the need for cross-sector collaboration. Other partners include Fujitsu Research of America, Inc., and Menten AI.

The hope, Safro said, is to bring the financial world to what is called practical quantum advantage, where processes are faster, more accurate and more energy efficient.

Finance is an area where even a small improvement will be felt literally in dollars, said Safro. Even a tiny improvement at the level of economy will be very significant. For example, it may amplify efficiencies across entire industries, leading to substantial cost reductions, enhanced productivity or more sustainable practices.

This is one reason finance is considered a major beneficiary of quantum computing.

Written for researchers who arent necessarily quantum computing experts, the team views the primer as a one-stop resource on the use of quantum computers to accelerate solutions for the finance sector. The paper discusses challenges in three categories at the intersection of finance and computing: optimization, machine learning and stochastic modeling.

We got together as a group of researchers from different institutions to better understand the state of the art of quantum computing for financial applications, said Marco Pistoia, head of Global Technology Applied Research at JPMorgan Chase. We wanted this to be appreciated by a larger audience. Our paper can be the starting point for researchers to better understand the landscape and then dive deeper in the areas that theyre interested in.

Quantum computing harnesses features of physics at the level of the atom to perform computations at speeds that leave traditional computing in the dust. In some cases, a quantum computer will be able to calculate in a few minutes what it would take a supercomputer 10,000 years to run.

The upside of quantum computing is absolutely humongous, said Argonne scientist Yuri Alexeev, one of the reports co-authors. Were talking about a potential speedup of millions of times for solving certain problems.

It is precisely the advantage of supersonic speed that finance experts are interested in.

In the financial world, time and accuracy are of the essence, Alexeev said. Getting solutions quickly can have huge benefits.

This could apply to everything from improving portfolio management to optimizing investment strategies to advancing the speedy detection of credit card fraud, to name just a few examples.

All these problems sound very general, but in fact, they are mathematical problems. Moreover, many of them are mathematical optimization problems, said Safro, whose expertise is in algorithms and models for quantum computing, machine learning and artificial intelligence systems, with a focus on natural language processing.

The three categories of challenges the paper discusses optimization, machine learning and stochastic modeling are at the intersection of finance and computing.

Optimization refers to methods for rapidly obtaining the best solution to a problem. For example, financial companies could use quantum computers to rapidly select assets that would provide the maximum return on a customers investment with minimal risk.

The second category, machine learning, is already a part of many financial institutions toolkits. In machine learning, computers draw on massive data sets to make predictions about various behaviors, such as patterns in the stock market. Combining quantum algorithms with machine learning can massively speed up those predictions.

The third category, stochastic modeling, is used across the sciences to predict the spread of disease, the evolution of a chemical reaction, or weather patterns. The mathematical technique models complex processes by making random changes to a variable and observing how the process responds to the changes. The method is used in finance, for instance, to describe the evolution of stock prices and interest rates. With the power of quantum computing behind it, stochastic modeling can provide faster and more accurate predictions about the market.

As the Nature Reviews Physics report makes clear, there is no shortage of finance challenges for quantum computers to tackle. Training the future workforce is a key part of solving future challenges.

UD is among the first higher-education institutions in the country to offer graduate and doctorate-level degrees in quantum science and engineering. Launched in 2023, the UD program offers three tracks: quantum nanotechnology, quantum theory or quantum algorithms and computation. Housed within the Universitys Graduate College, the interdisciplinary program is designed to equip next-generation quantum experts with skills expected to be in high demand, including algorithms, theoretical physics, engineering and nanoscale science.

According to Safro, one of the things that makes the field and ongoing research in this area exciting is the unknown.

Currently, there is no one specific quantum technology that we know for sure will take over the market, he said.

This means that multiple quantum technologies and vendors must compete to scale up quantum hardware, making it more powerful, reliable and accessible for broad use in scientific research to practical applications for a variety of industries.

Once researchers demonstrate practical scalability of quantum computing devices in one of these technologies, we will have an exact roadmap of how we build bigger and bigger quantum computers to tackle very large, real-world problems and how to hybridize them with classical supercomputers, Safro continued. With this literal breakthrough, I think the number of available jobs in quantum computing will explode, similar to what we have seen today with artificial intelligence.

This research was facilitated by the Chicago Quantum Exchange (CQE), an intellectual hub that brings together academia, government, and industry to advance quantum research, train the future quantum workforce and drive the quantum economy. Argonne and UChicago are founding members of the CQE, which is also anchored by DOEs Fermi National Accelerator Laboratory, the University of Illinois Urbana-Champaign, the University of WisconsinMadison and Northwestern University. JPMorgan Chase is a CQE corporate partner.

Protecting quantum computers from adversarial attacks – Innovation News Network

March 12, 2024 | Author: admin

The solution, Quantum Noise Injection for Adversarial Defence (QNAD), counteracts the impact of adversarial attacks designed to disrupt the interference of quantum computers. This is AIs ability to make decisions or solve tasks.

Adversarial attacks designed to disrupt AI inference have the potential for serious consequences, said Dr Kanad Basu, assistant professor of electrical and computer engineering at the Erik Jonsson School of Engineering and Computer Science.

The work will be presented at the IEEE International Symposium on Hardware Oriented Security and Trust on 6-9 May in Washington, DC.

Quantum computers can solve several complex problems exponentially faster than classical computers. The emerging technology uses quantum mechanics and is expected to improve AI applications and solve complex computational problems.

Qubits represent the fundamental unit of information in quantum computers, like bits in traditional computers.

In classical computers, bits represent 1 or 0. However, qubits take advantage of the principle of superposition and can, therefore, be in a state of 0 and 1. By representing two states, quantum computers have greater speed compared to traditional computers.

For example, quantum computers have the potential to break highly secure encryption systems due to their computer power.

Despite their advantages, quantum computers are vulnerable to adversarial attacks.

Due to factors such as temperature fluctuations, magnetic fields, and imperfections in hardware components, quantum computers are susceptible to noise or interference.

Quantum computers are also prone to unintended interactions between qubits.

These challenges can cause computing errors.

The researchers leveraged intrinsic quantum noise and crosstalk to counteract adversarial attacks.

The method introduced crosstalk into the quantum neural network. This is a form of Machine Learning where datasets train computers to perform tasks. This includes detecting objects like stop signs or other computer vision responsibilities.

The noisy behaviour of quantum computers actually reduces the impact of attacks, said Basu, who is senior author of the study. We believe this is a first-of-its-kind approach that can supplement other defences against adversarial attacks.

The researchers revealed that during an adversarial attack, the AI application was 268% more accurate with QNAD than without it.

The approach is designed to supplement other techniques to protect quantum computer security.

In case of a crash, if we do not wear the seat belt, the impact of the accident is much greater, Shamik Kundu, a computer engineering doctoral student and a first co-author, said.

On the other hand, if we wear the seat belt, even if there is an accident, the impact of the crash is lessened. The QNAD framework operates akin to a seat belt, diminishing the impact of adversarial attacks, which symbolise the accident, for a QNN model.

The research was funded by the National Science Foundation.

Cryptocurrency scams exploit the decentralized and pseudonymous nature of digital currencies, targeting unsuspecting users with various fraudulent schemes. Ponzi schemes promise high returns to early investors but collapse when new investors stop joining, leaving participants with losses. Phishing attacks impersonate legitimate entities through fake websites or emails to steal users private keys or passwords

Initial Coin Offering (ICO) scams entice investors with promises of revolutionary projects, only to vanish with their funds after fundraising. Pump and dump schemes artificially inflate a cryptocurrencys price before orchestrators sell off their holdings, leaving others with worthless assets. Exit scams involve fraudulent projects abruptly shutting down and absconding with investors money.

Fake wallets and exchanges deceive users into depositing funds, which are then stolen or inaccessible. Malware and ransomware attacks infect users devices, stealing their cryptocurrencies or encrypting data for ransom. Pyramid schemes rely on recruiting new members to sustain payouts to earlier participants, ultimately collapsing and causing losses. To mitigate these risks, users should exercise caution, conduct thorough research, and verify the legitimacy of projects and platforms. Implementing security measures such as hardware wallets, two-factor authentication, and vigilant password management can also help safeguard against cryptocurrency scams.

Overall, Web3 security measures offer a multifaceted approach to addressing the crisis of cryptocurrency scams by enhancing transparency, resilience, and user empowerment within decentralized systems. However, its important to recognize that no system is entirely immune to scams, and ongoing vigilance, education, and collaboration are key to mitigating risks effectively.

Instead of relying on centralized platforms, users can store their identity information on the blockchain and grant access selectively to different applications. This reduces the risk of data breaches and identity theft.

Permissioned Blockchains: While public blockchains offer transparency, permissioned blockchains allow for a more controlled environment. This can be beneficial for certain use cases where user access needs to be restricted for security reasons.

Biometric Authentication: Integration of biometric authentication methods like facial recognition or fingerprint scanning can enhance security for accessing Web3 wallets and applications.

3. Cryptography and Smart Contract Security:

Advanced Cryptographic Techniques: Web3 utilizes advanced cryptographic techniques like zero-knowledge proofs (ZKPs) to enable secure transactions without revealing sensitive information. ZKPs can be used for identity verification or financial transactions, enhancing privacy and security.

Smart Contract Audits and Security Tools: The rise of smart contracts in Web3 necessitates robust security measures. Formal verification techniques and security audits are becoming increasingly crucial to identify and mitigate vulnerabilities in smart contract code before deployment.

Bug Bounty Programs: Many Web3 projects are adopting bug bounty programs, incentivizing security researchers to find and report vulnerabilities in their protocols. This proactive approach helps identify and address security issues before they can be exploited by malicious actors.

Challenges and Considerations:

Novelty of Web3: Web3 is a nascent technology, and its security landscape is still evolving. New vulnerabilities and attack vectors might emerge as the ecosystem matures.

User Adoption and Awareness: For Web3 security to reach its full potential, widespread user adoption and education are essential. Users need to understand the security implications of self-custody and how to manage their private keys responsibly.

Interoperability and Standardization: The fragmented nature of the Web3 landscape, with various blockchain protocols and standards, poses security challenges. Interoperability and standardization efforts are crucial for creating a more secure and unified Web3 ecosystem.

Web3 security represents a significant step forward in securing the crypto landscape. By leveraging decentralization, cryptography, and a community-driven approach, Web3 offers a more secure and empowering environment for users to interact with the digital world. While challenges remain, the innovations introduced by Web3 have the potential to revolutionize how we approach security in the crypto space, paving the way for a more trusted and transparent future.

In conclusion, while cryptocurrency scams pose significant challenges to the integrity and trustworthiness of the digital asset ecosystem, Web3 security measures offer promising solutions to mitigate these risks and foster a safer and more resilient decentralized landscape. By leveraging blockchain technology, smart contract audits, decentralized identity solutions, and community vigilance, Web3 platforms can enhance transparency, accountability, and user empowerment in combating fraudulent activities.

Firewall Raises $3.7M to Take Smart Contracts Mainstream With Programmable Finality – FinSMEs

March 12, 2024 | Author: admin

San Francisco, USA / California, March 7th, 2024, Chainwire

Firewall, a blockchain infrastructure startup, announced its $3.7M pre-seed round, co-led by North Island Ventures, Breyer Capital, and Hack VC.

Firewall transforms the usability of smart contract technology through an innovative finality consensus mechanism that eliminates smart contract exploits.

The founders of Firewall, previously the first and sixth employees at Stakeda staking company acquired by Kraken in a landmark crypto dealhave helped breathe life into the eras of proof-of-stake and decentralized finance over the last six years. In that time, the founders served institutional clients with infrastructure that handled billions of dollars, and now building on their experience, are addressing what most perceive as the final major hurdle to a full embrace of digital assets by the traditional financial system.

Firewall is building the safety rails that enable the everyday person to use the next era of the Internet, stated Devan Purhar, Co-Founder of Firewall. Today, billions of dollars are stolen from users, through irreversible transactions that are classifiable as theft. Theres a parallel between the current state of crypto-networks and the early internet, with a similar lack of essential security infrastructure. Our focus is not on marginal improvements; rather, we bring a required paradigm shift in the usability of blockchains. We designed a solution from first principles, and created programmable finality. Fundamentally, we make exploits a concept of the past.

Akin to a digital version of a traditional networks firewall, Firewalls technology introduces programmable finality. It extends rollups to use programmable transaction finalization rules, which act as automated checkpoints that block harmful transactions, inserted before later stages when the data is finalized by a DA layer such as EigenDA or Celestia. The founders envision Firewall as a part of every smart contract network, acting as an embedded security system that intelligently guards against threats.

Firewall uses real-time algorithms to pre-filter exploits from being included in blocks, shared Sam Mitchell, Firewall Co-Founder. Then, by using programmable finality we automatically recover from any exploits that bypass the pre-filter checks. Detection at this stage can involve AI models or social consensus, which may take longer. Mitchell emphasized that institutions, managing trillions in assets, are interested in the benefits of smart contracts but require a secure environment to deploy capital. Creating comfort for institutional clients to use smart contracts will be the pivotal point for the widespread adoption of digital assets.

Past the founders, the core team is credited with successfully pioneering AI use in crypto threat detection at OpenZeppelin and Forta, and is set to revolutionize the field with Firewalls all-encompassing security approach. The startups initial focus is on the rollup ecosystem, and prides itself on alignment with building non-custodial and trustless solutions. The funding will help expand the team and create the community to firewall the EVM. Longer-term plans include developing coordination mechanisms to integrate the social layer directly into the Firewall.

Travis Scher, Managing Partner at North Island Ventures, said We believe the primary impediment to cryptos mainstream adoption is the current security paradigm, in which a single bug can lead to a total loss of user funds. Firewalls solution can prevent such losses, and we are thrilled to support such an important company from the outset.

The funding round was co-led by North Island Ventures, Breyer Capital, and Hack VC, with participation from Finality Capital, and angels including Tim Ogilvie of Staked, Kain Warwick and Jordan Momtazi of Synthetix, Nathan McCauley of Anchorage, and Yaoqi Jia of AltLayer.

Firewall is making blockchains safer for users, developers, and institutions, said Ted Breyer of Breyer Capital. We see this catalyzing a new era of smart contract utility, and were delighted to support the team.

With the growing global adoption of crypto and regulatory spotlight, catalyzed by the BTC ETF and anticipated ETH ETF, the time for crypto-networks to become bulletproof is now. Trillions of dollars remain on the sidelines, scared to use smart contracts. Firewalls programmable finality which effectively neutralizes exploits, offers the security assurance needed to unlock these assets, paving the way for crypto to revolutionize the global financial system.

About Firewall

Firewall is dedicated to making smart contract technology safe to use in everyday life, by eliminating smart contract exploits. Their solution is akin to a robust network firewall, applied to the modular blockchain ecosystem.

EigenLayer: ETH Restaking Strategy And Its Mechanics – CCN.com

March 12, 2024 | Author: admin

Key Takeaways

EigenLayer is a protocol built on the Ethereum blockchain network that introduces a new concept called restaking. EigenLayer gives developers access to Ethereums decentralized validator set and the large quantity of staked Ether ( ETH).

This enables them to create new apps that make use of the security architecture that is already in place. In addition to their normal staking payouts, stakers who choose to participate in EigenLayers smart contracts may receive additional rewards.

Heres what EigenLayer offers:

EigenLayer lets customers reuse their ETH if they have already staked it. This implies that they can get rewards beyond their initial staking earnings by using their staked ETH to secure other Ethereum-based applications.

EigenLayer effectively establishes a shared security pool when restaking is enabled. By extending Ethereums staker-provided security to new applications, this pool leverages existing security. This can help these applications by saving them the sometimes costly and time-consuming task of creating their own validator sets.

Because of EigenLayers restaking functionality, developers can now create new Ethereum apps that were previously unfeasible because of security constraints. This might result in the Ethereum networks ecosystem being more dynamic and inventive.

Three key elements make up the EigenLayer network: operators, restakers, and actively verified services (AVS). Restakers get incentives in exchange for contributing staked Ethereum or Ethereum liquid staking tokens (LSTs) to the ecosystem.

While individuals with ETH staked on liquid staking platforms can restake their LSTs through EigenLayer or liquid restaking protocols, users with ETH staked directly on the beacon chain can allow native restaking by creating EigenPods.

By enabling applications to work on the EigenLayer platform, operators are essential to the restaking process. In addition to enabling restakers to assign their stakes through EigenLayer enrollment, they may also provide support for other platform services. Furthermore, operators can function as restakers themselves, just like Ethereum validators do, guaranteeing the legitimacy of blockchain transactions.

Lastly, AVS include a range of technologies, including quick finality layers, data availability layers, and oracle networks, that call for special distributed validation processes. EigenDA is one of the initial AVSs being built in the EigenLayer ecosystem. It is a decentralized data availability layer designed to improve Ethereums scalability.

Blockchain security relies on a strong economic incentive for validators to act honestly. Traditionally, each new application on a network like Ethereum needs its own set of validators, which can be expensive and complex to manage. Additionally, theres nothing else one can do with this locked Ether. This fragmented security weakens the overall system.

EigenLayer tackles this by introducing restaking. Stakers whove already locked up their ETH for Ethereums security can opt-in to use that same staked ETH to secure other applications. This creates a shared security pool, leveraging the existing power of Ethereums validators.

EigenLayer facilitates this process through smart contracts, allowing applications to borrow security without the burden of individual validator sets. With the use of these contracts, users can secure other Ethereum-based apps with the ETH they have previously staked. In essence, this restaking gives these new applications access to the security that current Ethereum validators offer.

Its similar to utilizing your current staked Ethereum home security system (staked ETH) to protect your neighbors home (new application). Strong security is provided for the new application, which doesnt require any setup, and you, the stakeholder, may receive extra incentives for adding this extra protection.

Applications get strong security as a result, and stakers stand to gain financially. This not only strengthens the overall security of the ecosystem but also allows stakers to potentially earn additional rewards.

EigenLayers restaking mechanism enhances security by consolidating fragmented security pools, making malicious attacks significantly more costly than rewarding.

Through EigenLayer, slashing conditions are enforced via smart contracts managing withdrawal credentials for staked $ETH, ensuring that malicious activity results in slashing, with up to 50% of staked $ETH at risk. This framework maintains a robust security protocol, deterring potential attackers and safeguarding users assets.

While EigenLayer promises an innovative approach to security on the Ethereum network, its not without potential risks. Here are some key vulnerabilities to consider:

EigenLayer mostly depends on smart contracts to control the restaking process, which poses a risk. The security of staked ETH and the apps it protects may be jeopardized if these contracts have flaws or vulnerabilities that could be used by bad actors.

EigenLayers success depends on its uptake by stakeholders and application developers alike. EigenLayers shared security pool may not be as effective if developers are reluctant to trust the security model or if stakeholders view the rewards for restaking to be unappealing.

The laws governing cryptocurrencies are often evolving. EigenLayers profitability may be severely impacted if laws are put in place that limit staking or smart contract capability.

EigenLayer creates some concentration risk by combining security from a single source, Ethereums validators. Any application that makes use of EigenLayers restaking feature may become less secure if a serious flaw in Ethereums validator set is discovered.

EigenLayer presents a novel way to strengthen Ethereum network security by using its restaking mechanism. EigenLayer creates security pools by allowing stakers to use their locked ETH to secure various apps, thereby prohibitively expensive bad assaults. Smart contracts enforce this architecture, which upholds strong security protocols to ward off threats and protect users assets.

EigenLayer does, however, come with some risks and weaknesses in addition to its potential solutions. These risks include concentration risk, regulatory uncertainty, adoption volatility, and smart contract issues. Notwithstanding these difficulties, EigenLayers importance in the developing field of blockchain technology is highlighted by its ability to strengthen Ethereums security and encourage stakeholders.

EigenLayer introduces a novel approach to Ethereum security via its restaking mechanism, consolidating security pools and deterring malicious attacks.

Risks of restaking ETH in EigenLayer include smart contract vulnerabilities, uncertain adoption, regulatory challenges, and concentration risk.

No, withdrawal is not immediate in EigenLayer due to enforced slashing conditions and the restaking mechanism.

EigenLayer maintains security through enforced slashing conditions governed by smart contracts and consolidating security pools to increase the cost of malicious attacks.
