Physics Breakthrough: Researchers Overcome Long-Standing … – SciTechDaily

Research findings led by Paul Cassak, WVU professor and associate director of the WVU Center for KINETIC Plasma Physics, have broken new ground on how scientists can understand the first law of thermodynamics and how plasmas in space and laboratories get heated.

Physicists at West Virginia University have overcome a long-standing limitation of the first law of thermodynamics.

Paul Cassak, a professor and associate director of the Center for KINETIC Plasma Physics at West Virginia University, and Hasan Barbhuiya, a graduate research assistant in the Department of Physics and Astronomy, are investigating the conversion of energy in superheated plasmas in space. Funded by the National Science Foundation, their findings, published in the Physical Review Letters journal, are set to revolutionize the understanding of how plasmas in space and labs are heated and could have far-reaching implications in physics and other sciences.

The first law of thermodynamics states that energy can neither be created nor destroyed, but it can be converted into different forms.

Suppose you heat up a balloon, Cassak said. The first law of thermodynamics tells you how much the balloon expands and how much hotter the gas inside the balloon gets. The key is that the total amount of energy causing the balloon to expand and the gas to get hotter is the same as the amount of heat you put into the balloon. The first law has been used to describe many things including how refrigerators and car engines work. Its one of the pillars of physics.

Developed in the 1850s, the first law of thermodynamics is only valid for systems in which a temperature can be properly defined, a state known as equilibrium. As an example, when combined, a cup of cold water and a cup of hot water will eventually reach a warm temperature between them. This warm temperature is the equilibrium. However, when the hot and cold water have not yet reached that endpoint, the water is out of equilibrium.

Likewise, in many areas of modern science, systems are not in equilibrium. For over 100 years, researchers have attempted to expand the first law for common materials not in equilibrium, but such theories only work when the system is nearly there when the hot and cold water are almost mixed. The theories do not work, for example, in space plasmas, which are far from equilibrium.

The work of Cassak and Barbhuiya fills in the blanks on this limitation.

We generalized the first law of thermodynamics for systems that are not in equilibrium, Cassak said. We did a pencil and paper calculation to find how much energy is associated with matter not being in equilibrium, and it works whether the system is close to or far from equilibrium.

Their research has numerous potential applications. The theory will help scientists understand plasmas in space, which is important for preparing for space weather. Space weather occurs when huge eruptions in the solar atmosphere blast superheated plasma into space. It can cause problems like power outages, interruptions to satellite communications, and the rerouting of airplanes.

The result represents a really large step of our understanding, Cassak said. Until now, the state-of-the-art in our research area was to account for energy conversion only associated with expansion and heating, but our theory provides a way to calculate all the energy from not being in equilibrium.

Because the first law of thermodynamics is so widely used, Barbhuiya said, it is our hope that scientists in a wide array of fields could use our result.

For example, it may be useful for studying low-temperature plasmas which are important for etching in the semiconductor and circuit industry as well as in other areas like chemistry and quantum computing. It might also help astronomers study how galaxies evolve in time.

Groundbreaking research related to Cassak and Barbhuiyas is being carried out in PHASMA, the PHAse Space MApping experiment, in the WVU Center for KINetic Experimental, Theoretical, and Integrated Computational Plasma Physics.

PHASMA is making space-relevant measurements of energy conversion in plasmas that are not in equilibrium. These measurements are totally unique worldwide, Cassak said.

Likewise, the breakthrough he and Barbhuiya have made will change the landscape of plasma and space physics, a feat that doesnt happen often.

There arent many laws of physics Newtons laws, the laws of electricity and magnetism, the three laws of thermodynamics, and the laws of quantum mechanics, said Duncan Lorimer, professor and interim chair of the Department of Physics and Astronomy. To take one of these laws that have been around over 150 years and improve on it is a major achievement.

These new first principles result in non-equilibrium statistical mechanics as applied to plasmas is a great example of the academic research enabled by NSFs mission to promote the progress of science, said Vyacheslav Lukin, a program director for plasma physics in the NSF Division of Physics.

The Surprising Compatibility of Science and Faith – The Atlantic

To explain how I feel about outer space and how it shapes my worldview, I have to start with one of my favorite Bible verses: When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou hast ordained; What is man, that thou art mindful of him? and the son of man, that thou visitest him? For thou hast made him a little lower than the angels, and hast crowned him with glory and honour (Psalm 8:3-5, KJV).

Although Im a graduate student in theoretical particle physics, not astronomy, both give me a similar feeling: that we human beings are set among a seemingly unfathomable universe, one that I believe is divinely created for us, and despite our tiny size among the cosmos, we can begin to comprehend it. With our God-given reason (one of the things that I believe makes us in the image of God), we can model and measure things like black-hole collisions and the afterglow of the Big Bang despite our tiny position among it all.

Understanding physics and astronomy is the closest I believe any human can come to doing magic, and taking something that seems impossible to know, like measuring the speed of distant stars and galaxies, yet making sense of it, is an incredible feeling. When I consider this in the context of my faith, I believe that understanding the laws and behavior of the universe is one of the few times we can directly observe Gods handiwork. Indeed, looking up at the night sky, I see that humanity is crowned with glory and honour.

Despite sharing Carl Sagans sense of awe, I strongly disagree with significant parts of his prescription for how we should be humbled by our tiny place in the universe. No one claimed humanity is special because of its size. We human beings are tiny, but the things that make us uniquely humanour curiosity, reason, and understandingstretch across the limits of the physically observable universe. Because I believe the universe was intentionally created for us, I also believe its physical laws were made by God for us to discover. So, as a theoretical physicist in training, I intend to take God up on his offer.

But there are still things in science that make me humbled about humanitys place in the universe; theyre just in quantum mechanics, not astronomy. For all that astronomy gives me pride in when it comes to what humans have been able to understand, quantum mechanics throws understanding back in my face and, like God speaking to Job out of the storm in Job 38, tells me that there was never any promise that the universe was made so a human mind would be able to comprehend all of it.

What I value in humanity is not our size, but our minds (among other things), so when physics tells me that our understanding has seemingly insurmountable limits, that is when Im humbled by our place in the universe. Outer space gives me pride in humanitys scientific power and understanding; it gives me something visible that I can begin to wrap my head around and beautiful images that let me soak in the glory of creation. The realm of the very tiny is what inspires in me fear and trembling at Gods work and at human limits.

Podcast with Matt Johnson, CEO of QCWare – Quantum Computing Report

Transcripts

Yuval Boger: Hello, Matt. And thank you for joining me today,

Matt Johnson: Yuval, its great to be here. And thanks a lot for having myself and QCWare on your program.

Yuval: Its my pleasure. So who are you, and what do you do?

Matt: My name is Matt Johnson. I am a co-founder and CEO of QCWare. And what I do is help pull our team forward so that our business can be the first quantum computing software company that can yield practical quantum advantage. That is the objective of our company.

Yuval: Im curious about your personal journey. Youve been doing this for more than a year or two. How did you get into quantum, and how long ago was it?

Matt: Well, I honestly truly do not like to talk much about myself. I think our team is delivering all the value. Youve posed this question, and Ill answer it briefly, but in a nutshell, I was originally an officer in the military, and I was always enamored with aerospace and defense technology, and just technology generally. And after that, I had gone into finance, and specifically, I spent a decade or so in principle investing, private equity. And those two professional experiences were both fascinating, and I wanted to somehow bring them together as a next chapter. And it seemed to me that working as part of a team to develop a business around a new technology, thats the combined theme. I thought that would be very, very intriguing. And that took me to Palo Alto about eight and a half years ago to work with my fellow co-founders to set up QCWare, and weve been going ever since. So that takes us to today.

Yuval: Were seeing companies that were set up eight and a half weeks ago, or eight and a half months ago. What advice do you have as CEO for someone whos starting a quantum computing company?

Matt: Thats a great question. For quantum computing, I think that person should do a very thorough mapping of the industry. That person should study who is doing what across the technology stack, and be very sober and realistic and honest with themselves about what business prospect and technology they have that they really think is truly differentiated. And I think that exercise is more important today than it wouldve been five years ago when quantum computing companies and startups, in general, were getting money thrown at them. Now, were in a phase where all of us must deliver and will be measured as to whether our thesis about how valuable our business is, comparing that thesis to reality and you need to have a favorable conclusion or outside stakeholders have to, in order for you to attract employees and attract funding and then to attract customers.

So I think you should have a very sanguine view on this. Its an extremely crowded field right now, and theres tons of uncertainty around really the core kernel of what has to happen to spark, to make this industry really take off as a commercially viable thing is having a quantum computer, having hardware that is capable of delivering quantum advantage using the extant quantum algorithms out there. So absent someone coming up with an algorithm or a use case that can leverage 20 or 30 qubits and beat any classical machine out there, assuming that doesnt happen, the world of quantum computing or enterprise computing really does need a couple of hundred very, very high-quality qubits. Perhaps not error corrected, but high quality. So thats the spark that has to happen. And until that is the case, all the other parts of the technology stack like us as an application software vendor, we are waiting for that to happen. And it requires a lot of resourcefulness in terms of building a business, a software business when quantum hardwares not there.

Yuval: What do you say to customers when they say, Well, the hardwares not there. And I used to work for a software company, so Ive been faced with the same questions, but what do you say?

Matt: Well, we have a couple of customer bases. So for customers who say the hardware is not there yet, with them, if they engage with us, it usually is because that customer has a view that quantum computing hardware will get there, in the same way that machine learning and data analytics did get there and it did impact their enterprises. So these companies, these are very sophisticated Fortune 200 enterprises who are not just for quantum computing but for any emerging technology, are specing or investing small amounts of money to develop expertise in the technology, to figure out how it will fit into their compute workflows and how it might impact their business positively. And so thats what we do. Were really providing for them this very technical partnership where we are looking at candidate use cases, so compute bottlenecks they have, and figuring out if and how quantum computing can resolve those compute bottlenecks. For high-value business problems, to allow them to solve them more quickly. And so really, thats the gist of why a big enterprise today would hire QCWare.

Yuval: Quantum computing has gone through ebbs and flows. On one hand, the quantum computer is on the cover of Time, but on the other hand, theres talk of quantum winter. Do you see that enterprises are less likely to engage, given what they read in the news?

Matt: Well, thats a very explicit question. I think that there is enough momentum in the development of quantum computing hardware and technology, to convince these groups that quantum computing will come. But theres a lot of uncertainty around the timing and around the specific use cases that will be exploitable on quantum computers. And so I dont see any of these enterprises backing away and saying, Weve concluded that theres nothing there, and so were stopping investing. But theyre moderating investment. And frankly, as they get more information about where quantum computing hardware and algorithms are, thats helping them have more focus programs. And were certainly seeing a lot of that. Were certainly seeing a coalescing of attention in financial services, for instance, around a couple of use cases, and in drug discovery around a couple of use cases. So were certainly seeing that. But that was a very explicit question you asked around quantum winter, and so that would be my answer.

Yuval: How do you differentiate yourself as a company? My sense is that perhaps some years ago, there werent that many software companies, a customer could come to you and say, Hey, lets run some optimization on D-Wave, and see how it works. Do you feel like these days you have to develop your unique algorithms or provide value beyond we can help you get started with quantum computing?

Matt: Thats precisely correct. I would say there could be up to 200 quantum computing software companies. 200 companies that attest to having some sort of product or product vision around quantum computing. And so if you look at that, those are at Really, some companies are close to the bare metal and doing this very heavy-duty compilation and translation and error mitigation, and all of these stuff thats close to the hardware, close to physics. And then theres a number of middleware companies that are focused on optimizing, mapping or embedding of problems onto hardware, making optimal use of the hardware resources that are there. Theres that level. And then theres a level on top of that, which is the application layer. And we happen to be one of the players there, I think were certainly the largest by a substantial amount as measured by revenue and number of customers, both commercial and government.

So we would differentiate ourselves by, frankly our expertise at inventing and developing quantum algorithms that get baked into application software. In order to develop algorithms, quantum algorithms, it actually takes very deep expertise in quantum algorithm design. And to do that, you need to have a firm grasp of quantum mechanics, of linear algebra. You have to have done quantum algorithm proofs, typically. And so weve got a team of close to 50 individuals. And of those, around 40 of them are Ph.D. plus in those fields.

And so our differentiator, the reason people hire us is because they say QCWare seems to be the group that is best at looking at a practical problem that we have, looking at the mathematical structure of that problem, and figuring out how to extend an existing quantum algorithm or to build a new algorithm to allow that problem to be resolved on quantum hardware. So thats really how we differentiate ourselves. People come to us because theyre trying to answer the question, How do I get this problem runnable on quantum hardware, this real-world problem?

Yuval: If you look at the spectrum of solution development, you could look at one end at a completely custom job, everything is very specific to every customer. And on the other end of the spectrum, shrink-wrapped software, I go to Google, and I say, Give me the best directions from Palo Alto to San Francisco. Where are we in quantum software along that spectrum?

Matt: Right. If you look at completely bespoke versus completely shrink-wrapped or web-based, for quantum software, I would say were at step two or three of 10 steps. So were way over on the bespoke side still, and that applies to the entire industry. And I think part of that is obviously, there are only a specific subset of problems that appear to have speed-up potential on quantum hardware. Ill give you an example to eliminate the answer that I have. If you look at lets say pricing derivatives using Monte Carlo simulation to calibrate pricing models that are used by market makers or traders or investors to price securities, complex derivatives, every one of those firms does it a little bit differently.

So its very difficult to have a one size fits all abstraction that would satisfy all of those groups without any kind of customization. And as hardware matures, as more and more banks and insurance companies and market makers get into this, yeah, there will be that kind of standardization. But its an astute question that youve asked, and the reality is there is still a very heavy amount of this bespoke work being done, at least at the application layer. I think its different in middleware and close to the hardware layer, but yeah thats my view.

Yuval: If so much is custom or bespoke, how do you see the company scaling? So in five or ten years, do you see QCWare becoming a Deloitte? Instead of 50 individuals, youre going to have 50,000 individuals or 5,000 doing bespoke work, or do you see it moving towards this shrink-wrapped solution?

Matt: Actually, yeah its certainly the latter. And we started that rotation about a year ago. So this has all been part of our master plan where weve done something remarkable. Weve signed over 50 customer contracts over the last three and a half years or so with a number of Fortune 50, Fortune 100, Fortune 200 companies. This gave us insight into what products we should build, what software products we should build. And so what were doing in the second quarter of this year, we are launching two products that we will be announcing, I cant announce them yet, but theyre in two domains that lend themselves to being boosted eventually by quantum hardware. These products that were launching are going to be on AWS, and they are, in both cases running on high-performance classical hardware. So these are interim products that will allow quantum processing to be slotted into them.

But until that quantum hardware is ready, were going to be running on the most powerful classical hardware thats out there. Thats how were making this transition. And in fact Im from Minnesota originally, and I and the rest of the leadership team, I think Ill share the view that we want to have a very, very, very lean team, a very lean and mean team, and we want everyone on our team to be able to demonstrate true ROI. And if you keep that kind of yardstick out there, youll avoid in many cases the risk of over-hiring. So oddly, when you think about it, if you have In a perfect world, it looks like this for a SaaS company, a well-run SaaS company does about $1 million of revenue per full-time employee, a million per employee.

So you could argue that if a company like QCWare with lets say 45 employees, which is I think at last count what we have, you could argue, Well, if theyre all focused at building and selling products, you should be able to do 45 million of revenue with that base. Now, of course, people say, No. No, you need a lot more customers excited. You got to build this up. You got to overinvest ahead of this and in order Maybe thats true, but I want to see if I can prove and our leadership team can prove that you can run it a lot more leanly than that, that you can scale profitably.

Yuval: Do you have a favorite quantum hardware platform? And do customers come to you and say, Well, this algorithm is great, but Id like to see it run on IonQ and then compare it with IBM, and then run it on Quantinuum, and so on and so on? Or do you help them pick one and then run with it?

Matt: We do not have a favorite platform nor do our customers. We are obviously an independent software vendor, and our job is to give our customers the ability to have their problems run To make them runnable, their production size problems, eventually runnable on anyones hardware. So I think it is really fair to say and this isnt a marketing statement, we have very deep respect for everyone of the teams that are building quantum computers. These are brilliant teams, brilliant individuals, and theyre taking a variety of different approaches. There will be some number that will win and some number that will get consolidated into the leaders, and some that may just not be operating five years from now. But we dont care to even try to pick a favorite or something, we are just hopeful that all of these hardware companies are going to continue to make advances. And we just want to be for our customers, that software company that is helping them squeeze the most power out of these early generation machines, more power than any other software company can do for them. Thats really what were up to.

Yuval: We spoke a lot about customers, and Im curious if you could give me one or two specific customers that youre particularly proud of what you are able to do with them.

Matt: Well, first of all, our first couple of customers were Airbus and BMW, and these have been very long-dated engagements for us. And I mentioned those in particular, I love all of our customers. Those two customers have been with us for a very long time, coming up on, I dont know, four and a half, five years, something like that. And we have deep respect for them. We really love the partnerships. And in both cases, weve done a number of different use cases with them building up quantum computing use cases, that should be runnable with potentially significant speedup potential when the hardware gets there. So these problems that weve run have been ranged generally from machine learning and optimization. So Id cite those as being very interesting customers.

The other ones that we can mention are for instance, Roche, and Boehringer Ingelheim. We have a number I dont know which ones I can disclose. I can also disclose our investors, and in some cases, theyre also customers, so this will give you some more insight. Goldman Sachs, we can disclose as the customer, theyre also an investor. Citigroup, Koch Industries, Samsung, these are all investors that Im rattling off. Covestro is a customer and an investor. Thats a smattering. In total, as I mentioned, weve signed 50 plus customer contracts, and I think we have at last count something like 32 unique customers. So some of those has been repeats.

Yuval: What do you know today that you didnt know a year ago, or what has most surprised you over the past year as it relates to quantum?

Matt: A deeper understanding and appreciation of the complexity of building hardware, quantum computing hardware. It is truly like in football, like a battle of inches, its an incrementalist process. There tend not to be any particular breakthroughs, its just a lot of hard work. I didnt realize until a year, a year and a half or two years ago, really the extent of that. I just have developed a much deeper appreciation for it.

Yuval: Theres a lot of quantum investment happening in Europe, a lot of government investment. As a US company, do you have a challenge going after some of that money? Do you think that some of it is more limited to EU members, or do you think that the whole world is open to you?

Matt: I think its definitely very challenging. Weve received a couple of very small grants in Europe. I also think its probably quite symmetric, in the same way that I think US-domiciled firms have an advantage to go after US government contracts, except basic research where its really global. The US government on the basic research level wants to support technology development everywhere. But when you get into applied research and procurement, obviously being US-domiciled will help to get US money. And its the same way in the EU. So yeah, its very difficult on that side.

On the other hand, although you didnt ask this explicitly, we have an office in Paris and we are building up extremely strong relationships with our customers in Europe and with various government agencies and nonprofits. So there are rules and practices and policies that we obviously have to and happily abide by, but we recognize as a US company being in other parts of the world, we are not always going to be in the poll position to receive favors from those national governments.

Yuval: And as we come closer to the end of our conversation, I wanted to ask you a hypothetical, if you could have dinner with one of the quantum greats, dead or alive, who would that be?

Matt: One of the quantum greats? Well, I suppose it would be, this is a throwaway common, everyone says this, I guess it would be Richard Feynman. I would like to discuss with him where the field is right now, and whether he, back in 1982 when he published his seminal paper or announced that I think he published in 81 and then briefed it in 82, if things are developing in a way that he thought they would or what Yeah. So I guess that would be the answer. Yeah. Yeah. And Yuval, Id invite you to that dinner.

Yuval: Thank you very much. Matt, it was a pleasure. Thank you so much for joining me today.

Matt: Its been my pleasure. And you have a great day. Thanks very much.

There are 4 different types of multiverse – Big Think

The movie Everything Everywhere All at Once pretty much swept the 2023 Academy Awards. For those who have not yet seen it, the film hinges on the multiverse the idea that there exists a series of parallel dimensions that can be similar to our own reality, yet different in some way. Without spoiling the plot of the movie, its core theme is that one small change can make a significant difference in ones life and can even change the universe.

To take a trivial example, did you ever wonder how your life might have unfolded had you summoned the courage to talk to that unobtainable crush back in high school? Maybe it would have worked out. With the increased confidence that resulted from success, you might have gone on to be president. Small things can have a big impact.

The recent movie is a clear example of the multiverses impact in cinema, and it is not the only one. Movies and television have embraced the concept as a way to change existing franchises, perhaps most notably in the Marvel universe and in the more recent Star Trek movies. Its all great fun, but it does make you wonder. Is the idea of a multiverse scientifically reputable?

That is actually a very difficult question to answer, because the definition of multiverse is a bit of a shapeshifter it is taken to mean different things.

While there are many different ideas of multiverses, to give a sense of the ones scientists take most seriously, it might be best to start with the different types of multiverses made popular by theoretical physicist Max Tegmark, who said that there were four.

Tegmarks first type relies on space being extremely big indeed, perhaps infinite in size. While the visible universe is a sphere, centered on the Earth and about 92 billion light-years across, that is only the part of the universe we can see. If space is much bigger than that, then the many other pockets of space, where other stars and planets were formed, host incredible variety. And if space is infinite in size, then in one of those distant pockets there is a chunk of space that is a carbon copy of our own.

Perhaps more interesting, there is also a chunk of space that is exactly like our own, except that places version of you had the nerve to ask out that crush. These different realities are the first type of Tegmarkian multiverses and are the least speculative, relying only on the infinite size of space.

The second type of multiverse relies on inflation, a reputable physics theory that originated in the 1980s to explain some features of our universe for example, why space seems to look the same no matter which direction we look, and why space does not seem to be curved back in on itself.

Subscribe for counterintuitive, surprising, and impactful stories delivered to your inbox every Thursday

Basically, inflation theory says that shortly after the universe began, there was a very brief moment in which it expanded faster than the speed of light. This could explain why space seems flat, because if you take any shape, no matter how curved, and you expand it enough, it will look flat. That same physical reality allows Flat Earth advocates to claim the Earth is flat despite its being spherical after all, the curvature is slight. Inflation also explains why the universe seems so uniform no matter where you look. If you take a small bit of space in which everything is similar, and then you expand it quickly, the bigger space also will look similar.

While inflation has not been definitively proved, the scientific community has accepted it to be plausible.

Tegmarks third type of multiverse arises from the laws of quantum mechanics. In traditional quantum mechanics, statistical laws rule the universe. Everything is possible until we make a measurement. The most famous example is Schrdingers cat, a scenario that considers what happens if you put a cat in a box with a radioactive element, a glass vial of poison, and a Geiger counter that will break the vial if the element decays. Common sense says that the cat is either alive or dead, even if we do not know which. Standard quantum mechanics says that the cat is both alive and dead at the same time until you open the box and check.

However, there is a version of quantum mechanics that says when you look in the box, you actually generate two versions of reality, one in which the cat is alive and the other in which it is dead. This is called the many-worlds interpretation.

While this interpretation of the laws of quantum mechanics is not universally accepted, it is gaining some traction with scientists. In its account of multiverses, there is a constant proliferation where each decision causes another universe to come into existence. A somewhat different version tells us that all versions of reality exist. As we encounter decision points, we simply choose which reality we experience. It is certainly an interesting conjecture, and one that fascinates many introductory philosophy students.

Tegmarks fourth type of multiverse is one in which essentially everything is different. In the first three types of multiverses, the basic laws of physics are the same, but some parameters might have different values for example, maybe gravity is stronger in this universe and weaker in that. However, in the fourth idea, maybe the laws of physics are different in the other universes. Maybe cause and effect are different. Maybe those universes have different numbers of dimensions, like in the book Flatland by Edwin Abbott. When you allow for completely different physical laws, it is hard to imagine all the possible types of Type-4 multiverses that could exist.

When considering the idea of multiverses, it is imperative to be careful about the word. Multiverse means different things in different theories, and not all theories have anything to do with reality. Multiverses might be real, but before you can take the idea seriously, you have to define which kind of multiverse you are talking about.

Raman Research Institute breakthrough to make online transactions safe – The New Indian Express

Express News Service |Published: 02nd April 2023 11:14 AMExpress Illustration.

BENGALURU:A team of researchers from Bengaluru-based Raman Research Institute (RRI) has discovered a secure quantum communication link that is set to help India design and develop secure communication channels, especially for defence and strategic purposes, enhance cyber security and even make online transactions and remote electronic voting much safer. It has become the first Indian team to achieve this breakthrough.

According to experts, quantum communication protects data by using the laws of quantum physics, which allow quantum particles like photons to transmit data. The particles, called quantum bits, or qubits, are extremely fragile in the quantum state. If a hacker interferes when these particles are in transit, the latters fragility prevents a successful hacking as their attempt to persist, exposes them through signatures of their activity, helping identify the hacking process and alerting the cybersecurity mechanism to pull the plug on the data transmission.

The Indian breakthrough has come as part of the Quantum Experiments using Satellite Technology (QuEST) project for which RRI has been collaborating with the UR Rao Satellite Centre of the Indian Space Research Organisation (ISRO) since 2017.

The RRI researchers successfully achieved a secure quantum communication established between a stationary source and a moving receiver using Quantum Key Distribution, demonstrating that it can now pave the way for ground-to-satellite-based secure quantum communication in the future. This was done to simulate an earth-orbiting communication satellite and a stationary ground station with which it maintains communication links.

Info transmitted from static to moving source

The RRI team, led by Prof Urbasi Sinha at the Quantum Information and Computing (QuIC) lab at the institute, achieved this feat by deploying the indigenously-developed Pointing, Acquisition and Tracking (PAT) system.

The PAT assisted the ground-based source in tracking the moving receiver, in this case, a terrestrial vehicle, a few metres apart. The successful experimental demonstration was held at RRI in early March this year.

The present demonstration is in continuation to the QuIC labs QKD established between two buildings on the RRI campus using an atmospheric free space channel in February 2021, another first in India, according to the RRI.

Although the PAT system has been widely used in satellite communications, achieving the establishment of secure quantum key distribution using the PAT system between a stationary source and a mobile receiver was not achieved in India before, according to Prof Sinha.

EncounterQuest brings Bigfoot fans to Hamlet’s Cole Auditorium – The Richmond Observer

HAMLET Hundreds of cryptid enthusiasts trekked to Cole Auditorium this weekend for the inaugural EncounterQuest to share their thoughts on Bigfoot, aliens and other creepy creatures.

Rockingham Mayor John Hutchinson wearing a specially made T-shirt featuring the santer, a cat-like beast reportedly seen in Richmond County and other spots along the Yadkin-Pee Dee River basin in the late 1800s and early 1900s opened the event.

A cryptid is an animal like Bigfoot, the Loch Ness Monster and Mothman that has been reported being seen by multiple witnesses but is not recognized by the mainstream scientific community. The study of such creatures is called cryptozoology.

The guest speakers and several vendors had booths set up in the lobby, with more vendors stationed in the banquet room, down the hall and just outside the front doors, selling a variety of cryptid merchandise including T-shirts and sweatshirts, hats, socks, stickers, clocks, wood carvings and stuffed Sasquatches.

Vendors came from across the eastern half of the U.S., with the farthest being from Ohio the same as Justin England and Jay Wolber, hosts of the Cryptids of the Corn podcast.

The pair chose their topic from an online poll: giant centipedes.

Not only did the podcasters discuss reports of monstrous arthropods of the Ozarks, but also recognized giant centipedes from around the world that can grow up to 20 inches long.

Cryptopunkologist Kenney Irish kicked off EncounterQuest with a presentation of Dogman sightings.

Irish compared the modern encounters with older accounts of werewolves and referenced the work of the late Linda Godfrey, a journalist who covered the Beast of Bray Road in Wisconsin in the early 90s.

While most reported sightings have occurred in the north Midwest ranging from Ohio to Minnesota a Google map shows three reports in North Carolina: one each in Pamlico, Cumberland and Robeson counties.

Irish also had one witness an unnamed judge from Ohio deliver his personal account via phone, recalling being chased by an upright wolf-like creature as a teenager.

Squatch Watchers, a North Carolina-based group of Bigfoot hunters (no firearms involved, just cameras), followed Irish, with each member speaking about their experiences and how they became involved.

The group also introduced each of the speakers and gave out prizes during the event.Tate Fulbright of N.C. Squatch Watchers talks to the crowd.

Following the lunch break, adventurer Ron Morehead took the stage to talk about his experience in recording the Sierra Sounds in the early 70s and give his thoughts on the nature of Sasquatch, highlighted in his book, The Quantum Bigfoot.

Quantum physics, Morehead posits, can explain how a Sasquatch can seemingly disappear and how tracks abruptly stop.

Morehead said he believes the creature featured in the infamous film from Roger Patterson and Bob Gimilin from Bluff Creek, California, in 1967 is different from those he encountered in Californias Sierra Nevada Mountains in 1972 and 1974.

Retired Navy crypto-linguist R. Scott Nelson spoke about how his analysis and transcription not translation of the Sierra Sounds appear to show a spoken Sasquatch language. According to Nelson, one of the clips appears to be a conversation between a male and female Bigfoot.

As for the UFO/alien end of the spectrum, Derrel Sims presentation centered around the alien abduction and implant phenomenon and his belief in a hybridization program.

Members of local ghost-hunting group Pee Dee Region Paranormal also had a booth and gave a brief talk at the end of the event.

Organizers Kim Ristau and Jessica Mora thanked the vendors, speakers and attendees in a Facebook post Monday afternoon.

Words cannot describe just how amazing EncounterQuest was, they said in the post. Each of them (the speakers) brought a different perspective to each of their topics and they nailed it! We have heard nothing but wonderful things about how unique and amazing our speakers were.

The organizers plan to make EncounterQuest an annual event.

Supermassive black holes share a surprising link with subatomic … – Space.com

Scientists have discovered a surprising connection between the supermassive black holes that dwell at the hearts of most galaxies and dense walls of subatomic particles called gluons.

In terms of size, they couldn't be more different: Supermassive black holes can be billions of miles across, and the dense walls of gluons, known as color glass condensates (CGCs), are less than a billionth of a mile in diameter.

Yet a team of scientists from the Ludwig Maximilian University of Munich, the Max Planck Institute for Physics and Brookhaven National Laboratory has discovered that supermassive black holes and CGCs are similar in that they are made of densely packed, fundamental force carrier particles called bosons.

Related: Dead and alive at the same time: Black holes have quantum properties

For CGCs, these bosons are gluons, particles that carry the strong nuclear force responsible for "gluing together" elementary particles called quarks to form protons and neutrons, which make up the atomic nuclei of all ordinary matter. For supermassive black holes, the constituent densely crowded particles are gravitons, hypothetical particles that carry the force of gravity.

In both systems, the bosons are arranged in the most energy- and size-efficient configuration. This creates a high degree of order that is typical of both CGCs and black holes, with both systems packing in the maximum amount of quantum information possible about their constituent bosons, including their spatial distribution, velocity and collective forces.

Because the limits placed on quantum information are universal, researchers can learn more about one system of densely packed bosons by studying the other.

As a result, the secrets of distant and inaccessible supermassive black holes could be revealed by examining CGCs in labs here on Earth. In particular, scientists could look at the "gluon shock waves" created in CGCs during particle collisions to learn more about the gravitational shock waves that are produced when two black holes collide and merge to form an even more massive black hole.

CGCs are created when atomic nuclei are accelerated to near the speed of light and then slammed together. After these collisions, conducted at facilities such as the Relativistic Heavy Ion Collider in Upton, New York, the CGCs "melt" to form a nearly perfect liquid of quarks and gluons. While investigating this process to learn more about the strong nuclear force, the team found that gluons appear to organize themselves in a way that conforms to a universal limit on the amount of entropy, or disorder, that can exist in a system. The enormous conglomerates of gravitons that make up black holes are also believed to arrange themselves according to this limit.

This mathematical similarity suggests there is a correspondence between how black holes are born, reach thermal equilibrium with their environment and even how they may eventually decay, and how walls of gluons collide in nuclear collisions at near-light speeds.

The limit placed on entropy behind this similarity is related to a key feature of quantum information science (QIS) called maximal information packing. Therefore, to learn more about the connection between black holes and gluon walls, scientists must turn to QIS. In turn, the study of these systems could ultimately prove useful for the development of quantum computers, which depend on tightly packed cold atoms to perform calculations.

The team's research is published in the journal Physical Review D (opens in new tab).

University of Victoria pursues low harm cancer care research – Victoria – Times Colonist

UVic research on gold nanoparticles could make cancer treatments more effectiveand easier on patients

Intravenous (IV) chemotherapy cancer treatments come with a host of unpleasant side effects.

Cancer-fighting drugs are delivered via the bloodstream, impacting systems throughout the entire body, with only 0.1 per cent reaching cancer cells. Even a targeted treatment like X-ray therapy is often paired with IV chemotherapy, which increases side effects.

University of Victoria medical physicist professor Devika Chithrani aims to change this. After completing her PhD in quantum physics, Chithrani took a risk, switching to post-doctoral research in biomedical nanotechnology. She investigated a then-new technique: inserting gold nanoparticles (GNPs) into cells to enhance X-ray therapy. When X-rays collide with gold atoms additional electrons are released, increasing the damage to GNP-containing cancer cells. Chithrani narrowed in on the optimal gold nanoparticle size for cellular uptake, and published it in her 2006 paper, which has been referenced by other health researchers over 5,300 timesand counting.

To say Chithrani enjoys her work is an understatement. It doesnt feel like work this is like my hobby!

Chithranis group recently found extremely promising results using the chemotherapy drug docetaxel that sensitizes cancerous cells to radiation. Chithrani and her industry partner, Chris Tam of Integrated Nanotherapeutics, collaborated to target delivery by placing docetaxel in submicroscopic fat balls called lipid nanoparticles (LNPs). Unlike normal blood vessels, fast-growing tumors are leaky. So, tumors preferentially absorb and retain LNPs.

Chithrani also discovered that docetaxel pulls GNPs towards cancer cell nucleiright where it can best enhance radiation treatments.

Next, Chithrani plans to encapsulate both docetaxel and GNPs within LNPs. The Nanomedicines Innovation Network awarded Chithrani two grants, funded by Networks of Centres of Excellence (NCE) program, to improve delivery, targeting, and activation of chemotherapeutic drugs while decreasing side effects. Chithrani was awarded $200,000 to research a nanomedical approach to pancreatic-cancer radiation therapy.

A second grant, to use radiation to trigger the release of LNP payloads only at tumor sites for head and neck carcinomas, is a collaboration with UBC molecular biologist Pieter Cullisknown for encapsulating m-RNA in LNPs for COVID-19 vaccines.

Chithranis work is highly collaborative, and she chooses to avoid competitive aspects. I collaborate with many institutes: BC Cancer (Vancouver and Victoria), Mayo Clinic (Florida), Maryland School of Medicine (Washington), McGovern Medical School (Texas). Its not about whos going to win here. Its about how/what can we do here.

While precious-metal therapy may sound pricey, Chithrani notes that even a gold standard treatment must be cost effective. What will be the expense per patient? This is importantwe want to build something, but we must keep the healthcare system cost low. We estimate a complete six-week treatment would require less than $200 in gold.

Chithrani is also interested in the environmental impact of cancer therapies. The efficiency and effectiveness of treatments arising from her research could reduce the amount of time people require medical interventions. I really believe this kind of treatment can be more environmentally friendly.

And Chithrani isnt focussed solely on her impressive research program. She insists on teaching first- and second-year physics classes, where she can reach more students and have the most impact inspiring the next generation of scientists.

Chithrani developed an introduction to biomedical physics course at UVic and was recently nominated for the UVic Faculty of Science Teaching Excellence Award. I want to encourage those early students really get them thinking critically! If you want to be recognized, you must achieve something. So, I ask them What is your next level? How can you move yourself up?

Patients and oncologists can look forward to what Chithranis next level will bring. For more information on UVics cancer research, visit uvic.ca/research.

Crypto Whales Accumulating Ethereum Scaling Altcoin by the Millions, According to On-Chain Data – The Daily Hodl

On-chain data reveals that crypto whales are snapping up the native asset of a hot Ethereum (ETH) layer-2 project by the millions.

Blockchain-tracking firm Lookonchain says that digital asset manager Amber Group sent millions of dollars worth of Arbitrum (ARB) tokens to crypto exchanges OKX and Binance, where they could potentially be sold on the open market.

Two related addresses of Amber transferred 11.2 million ARB ($15.8 million), out of which, 7.3 million ARB ($10.3 million) was transferred to OKX and Binance and currently holding 4.47 million ARB ($6.3 million).

While Amber Group reduced its ARB holdings, Lookonchain says several crypto whales have been in the process of accumulating ARB. According to the analytics firm, one whale collected a total of 4,048,947 ARB worth $5.7 million from OKX and Binance within the last 48 hours.

A second whale received 4,099,517 ARB worth $5.78 million from OKX over the same timeframe. Meanwhile, a third crypto whale accumulated 1,003,798 ARB worth $1.41 million from crypto exchange Binance.

At time of writing, ARB is trading for $1.34, trading mostly sideways over the past week.

Lookonchain also recently spotted an Ethereum whale that staked nearly $100 million worth of ETH through a decentralized finance (DeFi) platform.

A whale staked all 53,024 ETH ($95.5 million) through Abyss Finance

Through on-chain data tracking, we found that the ETH of the whale was bought from Poloniex, Gemini, Bittrex and other exchanges in 2017 and 2018, with an average buying cost of ~$368.

Top Altcoins to Look Out for Next Week! Is It the Beginning of Altcoin Season? – Coinpedia Fintech News

In March, Bitcoins market dominance, measured by its proportion of total cryptocurrency market capitalization, increased significantly from approximately 44% to a peak of 48%. Despite a 22.7% rise in Bitcoins price over the same period, many altcoins underperformed or experienced negative returns. Nevertheless, a few altcoins may continue to display solid bullish signals in April.

As March has ended, investors are interested in knowing which altcoins to keep an eye on in April. At the moment, Ripple (XRP), Cardano (ADA) and Polygon (MATIC) appear to be the top contenders for resuming their bullish recovery in the upcoming week.

XRPs candlestick exhibits a long wick, indicating that the bears are fiercely guarding the $0.56 resistance. XRPUSDTs candlestick pattern formed an inside-day, signaling ambiguity among the bulls and bears. If the price drops below $0.5, the token may revisit the breakout point at $0.49, a crucial level to monitor, as a breach could prolong the correction to the 20-day EMA ($0.45).

As of writing, XRP price trades at $0.51, with a decline of nearly 5% from yesterdays performance. However, it is expected that the token will take support near $0.5 and initiate a fresh rebound this week. If XRP manages to surpass the resistance zone between $0.56 and $0.59, its price could ascend from its current level, potentially soaring to $0.65 and $0.80 the following week.

Cardano has been on a strong bullish trend for the past few days and is expected to surge more next week. Following two days of indecision, the bulls have succeeded in propelling Cardano above the resistance at $0.39. The price has now arrived at the critical resistance located at the neckline of the inverse head and shoulders (H&S) pattern.

ADA price is currently trading at $0.39, with a downtrend of over 1.5%. The positive territory of the RSI and the upward trend of the 20-day EMA ($0.36) suggest that the most favorable direction for Cardanos price is upward. If buyers successfully drive the price above the neckline, it would finalize the reversal setup, potentially propelling the altcoin towards its pattern target of $0.60 next week.

As the Polygon network is active in bringing robust network developments, traders may witness a skyrocketing trend in the MATIC price chart next week. Although Polygon briefly exceeded the 20-day EMA ($1.12), it encountered resistance from bears. As a result, sellers are likely to make an effort to drive the price down to the crucial support level of $1.04.

MATIC price is currently trading at $1.11, with a minor uptick. If the price surpasses and consistently stays above the 20-day EMA, MATIC could endeavor to reach the overhead resistance at $1.31.
