Viewpoint: Quantum computing and the nuclear industry : Perspectives – World Nuclear News

29 August 2023

A research project has highlighted the potential for quantum computing to deliver significant benefits for the design and operation of radiation facilities in the nuclear, medical and space industries, as Professor Paul Smith, Jacobs ANSWERS Technical Director, explains.

Modelling radiation transport is fundamental to nuclear physics and plays a part in everything from reactor design and operation, fuel fabrication, storage, transport, decommissioning and geological disposal. Beyond nuclear power and decommissioning, it plays a vital role in nuclear medicine, the space industry, food irradiation and oil well logging.

Monte Carlo codes are the reference method for creating simulations and solvingequations to understand the way in which physical energy is transferred by the absorption, emission and scattering of electromagnetic radiation - known as radiation transport.

The codes are designed to model and understand the movement and interactions of radiation particles (such as photons, neutrons, or charged particles) as they travel through different materials and interact with various structures.

There are two main approaches to solving the equations for radiation transport. In the deterministic approach traditional numerical methods are used to solve the mathematical equations -this involves a number of approximations. The alternative Monte Carlo approach involves simulating the paths of individual particles which involves less approximation but for some applications is prohibitively slow. In such cases it is used to produce high-fidelity solutions to test the accuracy of deterministic solutions which although more approximate, can be arrived at more quickly.

The ANSWERSSoftware Service, part of Jacobs, led a project to explore the potential benefitsof quantum computing in accelerating Monte Carlo methods.

Supported by the UKs National Quantum Computing Centres SparQ programme, which supports research into new applications, this project aimed to investigate the advantages of leveraging quantum computing instead of conventional digital computing to improve the runtime of Monte Carlo methods, making them more competitive.

ANSWERS provides and supports the MCBEND and MONK3D Monte Carlo codes which are widely used worldwide for radiation shielding, dose assessments, nuclear criticality safety and reactor physics analysis. For example, ANSWERS software is used to support the design and safety case production for transport flasks for radioactive materials.

Several processes contribute significantly to the computational cost of performing Monte Carlo radiation transport calculations including random number generation, nuclear database searches, ray tracing and the Monte Carlo process itself. Quantum algorithms are available or under development for each of these processes. Quantum random number generation has the clear advantage of generating truly random numbers, based on truly random quantum processes, whereas traditional computational methods are only capable of generating pseudo random numbers or quasi random numbers which can be subject to subtle correlations that can introduce bias into calculation results.

Whereas digital computers work with bits of data that are either 0 or 1, quantum computers work with qubits two-state quantum-mechanical systems that can be in a superposition of the 0 and 1 states. For example light may be horizontally or vertically polarised (try looking at an LED television through glasses with polarised lenses and tilting your head at different angles). If an individual photon of light is polarised at 45 degrees to horizontal it may be thought of as being in a superposition of the horizontal and vertical states.

This allows quantum computers to process many states in a single operation, increasing their processing power exponentially and achieving complex problem-solving which is impossible on digital computers. In practice, many quantum algorithms offer a quadratic advantage over traditional digital computers -for example, a quantum algorithm may achieve in 1000 operations what would take a million operations using a traditional algorithm.

There are certain scenarios where digital computing surpasses quantum computing. For instance, due to the specific ordering of nuclear databases (from lowest energy to highest energy), binary searches offer an exponential advantage over the quantum Grover search algorithm.

One of the biggest challenges faced by quantum computing at present is the presence of quantum noise. Being microscopic, quantum systems are very delicate.

Any interaction with the surrounding environment can change the state of the system, for example changing a qubit from state 0 to state 1 or vice versa. Random interactions with the qubits effectively add an element of noise to the answers obtained from a quantum computer. The project used Lucy, the Oxford Quantum Circuits computer, and was successful in demonstrating the effectiveness of new techniques for the reduction of quantum noise. This is currently an area of intense research activity.

The project partners - Jacobs, National Quantum Computing Centre (part of UK Research & Innovation), Oxford Quantum Circuits, National Nuclear Laboratory, Sellafield Ltd, and the University of Cambridge - note that there are promising signs that quantum algorithms could transform the computational aspects of ray tracing and Monte Carlo radiation transport simulation, but further research is needed to evaluate their applicability.

OneQuantum PH looks to demystify quantum computing through … – Rappler

This is AI generated summarization, which may have errors. For context, always refer to the full article.

'If you have a laptop, you can crack [a complex operation] in three hundred trillion years. A quantum computer with 4000 logical qubits can crack that in under ten seconds,' OneQuantum PH's president explains

Quantum computing community OneQuantum PH with CLASSIQ Technologies launched the Quantum Algorithms Design Workshop on August 10, one of its many skill-building initiatives aimed to make quantum computing projects accessible in the Philippines.

OneQuantums PH chapter started as a small Facebook group in 2017. Now partnered with the Department of Science and Technology Advanced Science and Technology Institute, they are set to lead the countrys first quantum computing hackathon later this year.

Other projects include talks with Bulacan State University in designing a quantum computing course and enhancing its computer science curriculum.

Quantum computing uses the unique principles of quantum mechanics, the physics of very small things, to create computers that can solve some complex mathematical problems years faster than current technology.

For Bobby Corpus Jr., president of OneQuantum PH, the technology can transform future strategies in tackling extensive computations for cybersecurity, agricultural simulations, infrastructure planning, and financial projections.

One thing about classical computing, he said, its nearing its limit.

There are several concepts that theoretically make quantum computing far more powerful than classical computing. One of these is called superposition.

In classical computing, bits are like pigeonholes that can only fit one pigeon at a time. They are capable of having one of two states: empty or full, 0 or 1. Binarys either-or ability enables the representation and processing of data.

Quantum computing, on the other hand, makes use of quantum bits, which are like pigeonholes that can fit many pigeons at the same time.

To illustrate, one qubit can simultaneously represent both 0 and 1. Two qubits can represent four states at the same time. A quantum computer with enough qubits can perform breakneck operations on very large numbers.

Corpus Jr. explains, If you have a laptop, you can crack [a complex operation] in three hundred trillion years. A quantum computer with 4000 logical qubits can crack that in under ten seconds.

The worlds highest-performing quantum computer has 433 qubits at present, made by IBM. The tech giant is also aiming for a 4000-plus-qubit quantum computer by 2025.

Despite the excitement surrounding quantum computing, Corpus Jr. points out that it is not a miracle cure for everything.

Today, creating quantum computers is an expensive pursuit, as they are incredibly sensitive to small disturbances in the environment.

Corpus Jr. believes that for the Philippines to truly benefit from this advancement, early preparations must be made to train the future workforce and secure the countrys information security before the technology is integrated into government and business practices.

In an introductory lecture, Corpus Jr. defined the goals of OneQuantum PH: to democratize quantum computing and remove its status as an ivory tower mystery in the Philippines. Ultimately, however, he believes that the fruits of their projects are for the future generation.

We believe that the future scalable, fault-tolerant quantum computer will be built by these kids in elementary schools. Thats why we pave the way for them. with reports from Jessica Bonifacio/Rappler.com

Whats up with Deutsche Telekom, BT and Infovista, Broadcom and VMware – TelecomTV

In todays industry news roundup: Deutsche Telekom has opened a quantum lab to explore the future secure communications networking options; Infovista helps BT with the automation of its fixed voice operations; Broadcom and VMware report sales increases ahead of their impending nuptials; and more!

Broadcom will be in a chipper mood right now. Following various regulatory approvals for its planned $61bn acquisition of VMware, it noted recently that its confident it can complete the deal by 30 October. Now both Broadcom and VMware have reported decent sales increases in their most recent financial quarters. For the third quarter of its fiscal year 2023, which ended on 30 July, Broadcom reported a 5% year-on-year increase in revenues to $8.9bn and an 8% increase in adjusted EBITDA to $5.8bn. Meanwhile, VMware reported a 2% year-on-year increase in second-quarter revenues to $3.41bn and a 1% increase in non-GAAP operating income to $977m.

Deutsche Telekom has opened a Quantum Lab in Berlin that is dedicated to quantum research and the integration of quantum technology into commercial telecommunications networks, the giant German operator has announced. The Berlin facility has dedicated infrastructure for quantum-optical experiments and is hooked up to 2,000 km of fibre networks that connect the lab to partners around Germany, including the Technical Universities of Berlin, Dresden and Munich, as well as the Fraunhofer Institut HHI and others from academia and the business sector. The opening of our Quantum Lab is a clear signal that we are serious about bringing quantum technology to the commercial networks of telecommunications providers, noted Claudia Nemat, chief technology and innovation officer at Deutsche Telekom. We explicitly invite the research and innovation community to join us in leveraging networks at the interface between R&D and commercial exploration like ours to prove that innovative quantum technology solutions work under real-world conditions and to usher in a new era of communications service, she added. This is far from DTs first foray into the quantum computing sector. Its enterprise services division, T-Systems, is already providing its customers with cloud access to IBMs quantum systems as part of its quantum-as-a-service offering, while DT was earlier this year handed the lead role in a European Commission project to build a high-security communications network, the European Quantum Communication Infrastructure (EuroQCI), which will be designed to protect the European Union (EU) against cyberattacks in the upcoming era of quantum computing. News of DTs Quantum Lab comes just days after SK Telecom, a very close R&D partner of DT, announced it is using an ITU security group meeting currently being hosted in South Korea to push for the development of global quantum-safe communications standards based on a combination of quantum key distribution (QKD) and post-quantum cryptography (PQC) technologies see SKT pushes for quantum-safe comms standards.

Telco automation comes in many forms, many of which can be filed under unglamorous but hugely important. In the UK, the incumbent national telco BT is taking steps to minimise fixed voice outages and service interruptions by introducing automated processes. It is deploying new technology from Infovista, the Paris, France-headquartered network lifecycle automation specialist. BT wants (and needs) the ability to rapidly identify the root cause of service disruptions as part of its drive to increase operational efficiency and customer satisfaction. In a press release about the deployment, Infovista noted that for BT it has leveraged its existing Ativa for Fixed Voice assurance solution to develop a tailored solution that will focus on the automation of RCA [root cause analysis] and notification, improving troubleshooting through intelligent pattern discovery, correlation, analysis and alarm generation. The expectation is that Infovistas solution, by promptly detecting network anomalies associated with network degradations within BTs infrastructure, will reduce current response times to network problems by very quickly identifying the root causes of customer or service disruptions. This, in turn, should reduce the all-important mean time to resolution (MTTR) metric by up to 66% while simultaneously transforming the troubleshooting processes in BTs trouble-ticketing system. In detail, the Infovista technology provides automated workflows for issue detection, analysis, and alarm generation, providing relevant data to streamline network, service, and subscriber issue troubleshooting. The move from manual to automated operations does away with the need for initial level 1 support and fast-tracks direct escalation to level 2 teams, as, when and where required. Reza Rahnama, BT Groups managing director for mobile networks, noted: BT is committed to developing and delivering next-generation services that continue to put our customers at the core of what we do and to deliver better outcomes. This means digitally transforming our own operations and using the power of automation across our network, infrastructure, services and operations.

US fixed wireless access (FWA) network operator Starry, which filed for Chapter 11 bankruptcy protection in February this year, has come out the other end of the process, having agreed a restructuring plan with the bankruptcy courts in May. We said from the beginning that Starry would emerge from this restructuring process stronger and ready to meet the growing demand for high-quality internet services, noted the companys CEO Alex Moulle-Berteaux. Today, as we exit this process, Starry is a stronger company. We are more operationally efficient and laser-focused on driving this business to profitability. Im immensely proud of all of our employees, who kept their focus on our customers, our network and on delivering an internet service experience that far outshines our big internet competitors. Im excited for this next phase of company growth and success for the company. The company also published a blog about what the end of the Chapter 11 period means for customers and the company.

Lets hear it for Ethernet, the ever-popular, proven and trusted suite of cabled computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). Around for decades before Wi-Fi, Ethernet was for a long time THE way to link computing and comms devices together. The technology was commercially introduced back in 1980 and was initially standardised (as IEEE 802.3) in 1983. Since then, Ethernet has seen off competing wired LAN competitors, such as ARCNET and Token Ring. And, even today, Ethernet retains advantages over Wi-Fi, in that it can be faster, more robust, stable and secure. It has also been repeatedly tweaked to carry increased bit rates, support a higher number of nodes and link longer and longer distances while continuing to retain backward compatibility. And now Ethernet is getting another vote of confidence as, in the US (and elsewhere too), service providers are further increasing Ethernet speeds and reach in response to demand from their business and wholesale customers. The demand is for 100 Gigabit Ethernet connectivity as enterprises and wholesalers upgrade their wired services and explore optical wavelength and dark fibre solutions. According to specialist optical networking publication Lightwave, Customer demand for retail wavelength circuits continued to outpace wholesale deployments in 2022 due to the surge in gigabit bandwidth requirements from carriers, webscale network operators and enterprises. In the US, service providers, such as Cogent, Lumen and Windstream, are reacting quickly to the increased demand and are boosting their networks (either through organic growth or via acquisition) to support more optical wavelength services. For example, Lumen Technologies is expanding its US intercity dark-fibre network to 12 million fibre miles and creating diverse routes to more than 50 major cities nationwide. It also plans to expand its network further over the next five years. And it has built out its 400Gbit/s wavelength network and has deployed its intercity wavelength network across 70 markets, giving customers a multiplicity of routing options. More than 240 datacentres are enabled for 400G Lumen Wavelength Services, and its network boasts more than 800 Tbit/s of capacity. The independent research house Vertical Systems Group, based in Medfield, Massachusetts, says the wavelength circuits sector is enjoying double-digit growth with demand for connections of 100Gbit/s or more expected to remain stratospheric until at least the end of 2027. Whats more, demand is also ramping up for services running at 400Gbit/s or more. And in addition to the impressive demand for wavelength and fibre-optic services, the continuing growth of Ethernet is acting as a foundation for next-gen dedicated internet/cloud access (DIA) and SD-WAN services. Rick Malone, principal of the Vertical Systems Group, wrote in the companys half-annual US Carrier Ethernet Services Leaderboard report that Ethernet port demand is being driven by the increasing use of DIA and SD-WAN services.

Intel is to invest $1.2bn in its production facilities in Costa Rica over the next two years to ensure its product assembly, research and development (R&D) and global services operations are ready to manage the companys latest technical innovations, the chip giant announced in a press release (published in Spanish).

Fascinating news from down under, where research scientists of the School of Physics and the School of Chemistry at the University of Sydney have used a quantum computer to slow down a simulated chemical reaction by an order of 100 billion! The research team at the Sydney Nanoscience Hub were able, for the first time in history, to directly observe the entire critical process in chemical reactions. The successful experiment was achieved by using a trapped-ion quantum computer in a way never attempted before. A trapped-ion quantum computer is one of several possible practical approaches to the construction of a universal large-scale quantum device. In such a device, ions (charged atomic particles) can be confined and suspended in free space using electromagnetic fields. Trapped ions have relatively long coherence times, which means that the qubits last a long time too. In the experiment, researchers were able to observe the interference pattern of a single atom caused by a common geometric structure in chemistry called a conical intersection. These conical intersections are known and commonplace throughout chemistry and are critical to rapid photo-chemical processes, such as light harvesting in human vision or photosynthesis on plants. Since as far back as the 1950s, many attempts have been made to directly observe geometric processes in chemical dynamics but the sheer speed of the reactions made it impossible. Now, however, it is possible to map the process onto a quantum device and then slow down the process by a factor of 100 billion. One of two lead authors of the project, Dr Christophe Valahu of the School of Physics, said, Until now, we have been unable to directly observe the dynamics of [the] geometric phase; it happens too fast to probe experimentally. [However] using quantum technologies, we have addressed this problem. Our experiment wasnt a digital approximation of the process this was a direct analogue observation of the quantum dynamics unfolding at a speed we could observe. Lead researcher, Vanessa Olaya-Agudelo of the School of Chemistry added, In nature, the whole process is over within femtoseconds. Thats a billionth of a millionth or one quadrillionth of a second. Using our quantum computer, we built a system that allowed us to slow down the chemical dynamics from femtoseconds to milliseconds. This allowed us to make meaningful observations and measurements. This has never been done before. She added, By understanding these basic processes inside and between molecules, we can open up a new world of possibilities in materials science, drug design, or solar energy harvesting. It could also help improve other processes that rely on molecules interacting with light, such as how smog is created or how the ozone layer is damaged. The research findings are published in the latest edition of Nature Chemistry.

Clemson mathematicians’ collaborative digital signature is a … – Clemson News

August 28, 2023August 28, 2023

A digital signature developed by researchers from Clemson University and three universities in Europe could become part of the national standard for encryption tools designed to protect the privacy of digital information against quantum computers in the future.

The U.S. National Institute of Standards and Technology (NIST) is holding a competition to select standard post-quantum digital signature algorithms that would securely authenticate email, credit card and bank transactions, and digital documents from unwanted third parties tampering.

The researchers CROSS (Codes and Restricted Objects Signature Scheme) proposal was named a candidate for standardization.

Now, researchers from around the world will try to break it.

If you think about it, this is the best way to choose the standards, said Felice Manganiello, an associate professor in the Clemson School of Mathematical and Statistical Sciences and one of the developers of CROSS. Once they decide which proposals are the candidates, the rest of the world can try to attack them to find vulnerabilities. These systems are secure until they are not anymore. So, these competitions are actually a healthy way to decide the standard by having a lot of people working on proving the security.

Clemson graduate student Freeman Slaughter and researchers from Polytechnic University of Marche,Polytechnic University of Milanand Technical University of Munich also worked on the proposal.

Quantum computers could revolutionize the future of fields such as medicine, finance, energy and transportation by solving complex problems that are beyond the reach of even the best of todays classic supercomputers.

Unlike conventional computers that perform computation and store information in binary form (1s and 0s), quantum computers exploit the strange properties of quantum physics to operate on information in multiple forms known as qubits. By leveraging two key phenomena quantum superposition and entanglement quantum computers can explore multiple solution pathways simultaneously, allowing them to solve problems that would take a classic computer too long to calculate.

With that power would come the ability to crack todays standards for encryption and digital signatures, which rely on math problems that even a combination of the fastest conventional computers find intractable.

The standards we have today would not be sufficient, Manganiello said.

The NIST announced the first group of three digital signatures in July 2022 after a multi-year vetting process. It called for additional digital signature proposals in 2022. About 50 proposals were received and 40 were named candidates.

A digital signature is a mathematical algorithm used to validate the authenticity and integrity of an email, credit card transaction or digital document. Digital signatures create a virtual fingerprint that is unique to a person or entity and are used to identify users and protect information in digital messages or documents.Digital signaturesare significantly more secure than other forms of electronic signatures, according to the Cybersecurity and Infrastructure Security Agency.

Six of the digital signature candidates are code-based signatures, including CROSS.

Manganiello said that after the NISTs first call for proposals several years ago, researchers realized that code-based cryptography was not competitive because it led to large signatures.

The code-based problems were the oldest and safest problems, but they were leading to very large signatures. That made the whole community start working on what could be done to decrease these signature sizes, he said.

While CROSS is code-based, it uses Merkle trees and zero-knowledge protocols to make the signatures shorter.

Our digital signature algorithm is competitive because the signatures are quite small and the speed of computing them is faster with respect to the other candidates, he said. The only issue is that the system is based on a more recent problem than others and theres not as much literature attacking it, he said.

Manganiello said it could take several years for the NIST to decide whether the researchers algorithm will be selected as a standard.

ESPOO, Finland , Aug. 30, 2023 /PRNewswire/ -- VTT is developing a cooling technology based on microelectronics and electric current, which can be utilised by low-temperature electronic and photonic components. The new technology reduces the size, power consumption and price of cooling systems. The method has a wide range of application fields: one topical example is quantum technology.

Many electronic, photonic and quantum technology components require cryogenics, as they only operate at very low temperatures. For example, a quantum computer built from superconducting circuits has to be cooled near to the absolute zero (-273.15C). Currently, such temperatures are achieved by complex and large dilution coolers. VTT's electronic method can replace and complement existing solutions and thus reduce the size of the refrigerators. Accordingly, this makes it possible to significantly reduce the size of quantum computers.

Electronic method as a part of the cooling system

Current dilution refrigerators are based on multistage pumping of cryogenic liquids. Although these coolers are commercial technology today, they are still very expensive and large. What makes the cooler technology complicated is especially its coldest stage, where refrigerant is a mixture of helium isotopes. New electric cooling technology could replace this part. This would make the system much simpler, smaller, more efficient and more cost effective. A cooler the size of a car, which cools a silicon chip of about a square centimeter in size, could be shrunk by orders of magnitudes down to a size of a suitcase, for example.

"We believe that this purely electric cooling method can be utilised in numerous applications requiring cryogenics, from quantum computing to sensitive radiation detectors and space technology," says VTT Research Professor Mika Prunnila , who is leading the cooler development.

New business opportunities

VTT researchers have already experimentally confirmed the functionality of the cooling method. The method is now being refined into a commercial demonstrator in SoCool-project which was granted to VTT in the highly competitive EIC-Transition program of the European Commission. VTT will also continue the highly important fundamental research of electronic coolers in the CoRE-Cryo-project, funded by the Technology Industries of Finland Centennial Foundation.

Electric cooling can be used to actively cool components directly on a silicon chip or in large-scale general purpose refrigerators. It is a platform technology that is suitable for numerous applications and creates opportunities for new business. The active part of the cooler is manufactured using microelectronics manufacturing methods on silicon wafers, which makes the manufacturing very cost-effective.

"Making the refrigeration systems more user friendly, smaller and cheaper can significantly boost the application of cryo-enabled technologies to new areas. We see that our electronic cooling technology can play an important role in this development," Mika Prunnila says.

Cryogenics has become an area of increasing interest thanks to quantum technology. Systems developed for the extreme demands of the quantum technology can be also used in various sensors, space technology and possibly also in classical computing. Compact and easy-to-use cooling methods contribute to the large-scale adoption of these technologies. Quantum technology is expected to be only the tip of the iceberg for cryogenic, cryo-electronic and cryo-photonic applications.

UBC electrical and computer engineering expert named Canada … – UBC Applied Science

Dr. Olivia Di Matteo, an assistant professor in UBC's department of electrical and computer engineering(ECE), has been awarded a Tier 2 Canada Research Chair (CRC) in Quantum Software and Algorithms. Sheisone of 15 UBC researchers appointed to a new Canada Research Chair.

The Canada Research Chairs Program (CRCP) is part of Canada's national strategy to be one of the world's top countries in research and development.Chairholders improve our depth of knowledge and quality of life, strengthen Canada's international competitiveness, and help train the next generation of highly skilled people through student supervision, teaching, and the coordination of other researchers' work.

Tier 2 Chairs are tenable for five years and renewable once. These are awarded to exceptional emerging researchers acknowledged by their peers as having the potential to lead in their field. New Tier 2 chairs receive a $20,000 annual stipend for research.

Di Matteo's work spans developing and implementing new methods for characterizing quantum systems, synthesizing quantum circuits, and applications of quantum computing in physics, as well as many contributions toPennyLane, an open source quantum software framework that other researchers use for their own work.

She speaks about her work at ECE and future research plans (full interview).

My group works on quantum software and algorithms, so the day-to-day is a lot of programming. On the software side, one area of focus is developing tools for automating and improving quantum compilation, which is the pipeline that translates high-level algorithms into the language of quantum hardware. On the algorithms side, we are exploring the potential use of qutrits (instead of qubits) in quantum algorithms and working on some techniques for noise mitigation.

That there are problems that are hard even for quantum computers. There's a serious amount of hype around my field right now, and quantum computers are often presented as super-advanced machines that will solve every problem exponentially faster. There are definitely some specific (but important!) problems for which we expect this will be the case (once we overcome the major engineering hurdles of building them, of course). But there are classes of problems we believe will remain hard.

Lately, I've been diving into some applications of quantum computing to nuclear theory and particle physics, which has been really fun, since my training is actually as a physicist. The mapping of those problems to quantum algorithms in software through the compilation and optimization process is really interesting, and I'm hopeful that with some advances on the software front, we'll soon be able to leverage the hardware to solve more realistic problems.

I'm also thinking about how we can make quantum computing software more accessible (e.g. through better abstraction and helpful debugging tools), so that more people can use the technology in their own work.
