The Animated Map of Quantum Computing: A Visual Introduction to the Future of Computing – Open Culture
If you listen to the hype surrounding quantum computing, you might think the near future shown in Alex Garlands sci-fi seriesDevs is upon us that we have computers complex enough to recreate time and space and reconstruct the human mind. Far from it. At this still-early stage, quantum computers promise much more than they can deliver, but the technology is poised, writes IBM to transform the way you work in research. The company does have as do most other other big makers of what are now called classical computers a roadmap for implementing quantum computing and a lot of cool new technology (such as the quantum runtime environment Quiskit) built around the qubit, the quantum computer version of the classical bit.
The computer bit, as we know, is a binary entity: either 1 or 0 and nothing in-between. The qubit, on the other hand, mimics quantum phenomena by remaining in a state of superposition of all possible states between 1 and 0 until users interact with it, like a spinning coin that only lands on one face if its physically engaged. And like quantum particles, qubits can become entangled with each other. Thus, Quantum computers work exceptionally well for modeling other quantum systems, writes Microsoft, because they use quantum phenomena in their computation. The possibilities are thrilling, and a little unsettling, but no ones modeling the universe, or even a part of it, just quite yet.
Use cases are largely experimental and hypothetical at this early stage, McKinsey Digital writes in a report for businesses, while also noting that usable quantum systems may be on the market as early as 2030. If the roadmaps serve, thats just around the corner, especially given how quickly quantum computers have evolved in relation to their (exponentially slower) classical forebears. From the first idea of a quantum computer in 1980 [an idea attributed to Nobel prize-winning physicist Richard Feynman] to today, there has been a huge growth in the quantum computing industry, especially in the last ten years, says Dominic Walliman in the video above, with dozens of companies and startups spending hundreds of millions of dollars in a race to build the worlds best quantum computers.
Walliman offers not only a (non-hyped) map of the possible future, but also a map of quantum computings past. He promises to clear up misconceptions we might have about the different kinds of quantum computing, how they work, and why so many people are investing in the quantum computing industry. Weve previously seen Wallimans Domain of Science channel do the same for such huge fields of scientific study as physics, chemistry, math, and classical computer science. Here, he presents cutting-edge science on the cusp of realization, explaining three essential ideas superposition, entanglement, and interference that govern quantum computing. The primary difference between quantum and classical computing from the point of view of non-specialists is algorithmic speed: while classical computers could theoretically perform the same complex functions as their quantum cousins, they would take ages to do so, or would halt and fizzle out in the attempt.
Will quantum computers be able to simulate nature down to the subatomic level in the future? McKinsey cautions, experts are still debating the most foundational topics for the field. Despite the industrys rapid growth, its not yet clear, Walliman says, which approach among the many he surveys will win out in the long run. But if the roadmaps serve, we may not have to wait long to find out.

Government’s next big task? Avoiding the quantum computing pitfall – Open Access Government
For more than fifty years, public key infrastructure, or PKI, has been relied upon by almost all organisations to provide the cryptographic backbone which secures devices and the humans using them.
Relatively unknown outside the technology industry, PKI digital certificates provide the digital trust needed to secure critical national infrastructure from telecommunications to energy supply, the banking sector and even life-critical technology deployed by armed forces worldwide.
Without PKI, public and private network access would not be safe, or secure. Only with PKI can we ensure the devices, people, software, and applications that make up critical national infrastructure remain in the sole control of those trusted with their security. PKI relies mainly on two algorithms, which form the basis of current cryptography: the RSA 2048 (Rivest Shamir Adleman) and ECC 256 (elliptic-curve cryptography).
These algorithms are the foundation of the digital stamps which verify and protect human and non-human, or machine identities used to access sensitive data across government and all industries. However, change is coming.
Like most things, nothing lasts, and the PKI organisations the world over have relied upon to maintain digital trust has an emerging and very real threat. We are now standing at the precipice of a new age of quantum computing; an advanced type of computation that leans on quantum physics to run multiple processes simultaneously. Quantum computing will render traditional PKI, as we know it, no longer fit for purpose.
This poses a very real threat to the information security systems we all rely on to protect our freedom and liberty. To remain secure, government agencies will have to adopt new families of quantum-resistant cryptography.
Now is the time to prepare for this transition. The step-change quantum computing will bring cannot be underestimated. The average computer trying to break a message encrypted with our common RSA and ECC algorithms would need around 300 trillion years. A quantum computer, with its ability to guess keys in parallel, would need around a week.
The effects will be dire; when the first quantum computer becomes powerful enough, even data under the highest encryption will become easily decrypted by whoever has access to a functional quantum computer. In fact, some adversaries are already saving encrypted content, that they will later look to break with quantum computers (and perhaps other methods).
This could be anything from the control systems upholding the national electric grid, remote devices controlling the water supply, systems operated by the armed forces or secret services, even the central banking system. Scientists consider the predicted fallout of quantum computers so severe its called the Quantum Apocalypse.
Given the gigantic steps forward in the research and development of quantum computers, with Google, Honeywell, and indeed China in the race, it is a matter of when rather than whether quantum computers will change the digital world as we know it. One thing is certain: Governments must implement new cryptographic alternatives as soon as possible.
Work is already underway to overcome this looming issue: The USAs National Institute of Standards and Technology (NIST) is working to find quantum-resistant alternatives to our current algorithms. Organisations across the world, from the fields of academia, technology, and the public sector, have united to collaborate in the discovery of new, quantum-safe algorithms.
NIST coordinates their efforts, and its Post-Quantum Cryptography project is well en-route to identifying and vetting potential next-generation cryptographic schemes, which it expects to do by 2024. Even before the NIST arrives at its final candidates, government agencies must begin the transition to quantum-safe PKI certificates to withstand the Quantum Apocalypse.
This process presents the core challenge: replacing every one of the trillions of certificates and keys in circulation in our digital systems is a gargantuan task given the variety of types, sources, issuers, lifespans, and a myriad of other factors. For every government around the world, this is mission-critical: failure to replace even one certificate could lead to breaches, data exfiltration, or operational disruption.
The first step is to gain a full understanding of all certificates and keys present in the public environment, and enable government IT to replace them at will, regardless of their specificities. The only way to make this shift effectively and safely is to leverage crypto-agile automation.
That is a crypto-agile approach, which anticipates frequent changes across, potentially, millions of certificates, keys and cryptography. One example, as it pertains to certificates is with Certificate Lifecycle Management. This allows organisations to manage all the certificates in the enterprise system at once, renewing, deploying and revoking them as necessary. Deploying these CLM solutions now can ease the transition to quantum-resistant certificates.
The most advanced CLM solutions can manage the transition of all certificates, independently of their particulars, including which Certificate Authority issued them originally. This makes CLM extremely effective in the transition from existing PKI certificates to quantum-resistant ones, as it ensures no stone will be left unturned.
While the cryptographic community works to standardise quantum-safe algorithms, players who have been securing the digital systems since the dawn of the internet have published free sets of resources like Quantum Labs.
Organisations and governments must arm themselves with the tools to migrate to quantum-resistant algorithms and prepare for the quantum era. In this way, they face the quantum era as a leap forward, not a jump into the void.

USC ISI works with D-Wave to house one of the First US-Based Advantage Quantum Computer – USC Viterbi | School of Engineering – USC Viterbi School of…
The D-Wave Advantage quantum system.
LOS ANGELES (May 12, 2022) USC and D-Wave Systems Inc. are launching the first 5,000+ qubit D-Wave quantum computing system physically located in the United States, designed for academic researchers, government users, and business clients, the Advantage quantum system. Other systems are located in Germany and Canada.
As part of the USC-Lockheed Martin Quantum Computing Center (QCC) hosted at the USC Viterbi School of Engineerings Information Sciences Institute (ISI), the Advantage system is accessible via the Leap quantum cloud service.
The new system contains the Advantage performance update released in October 2021, featuring the highly connected Pegasus topology and 5,000+ qubits.
The D-Wave Advantage quantum annealer is the largest scale programmable quantum information processor currently available anywhere, said Daniel Lidar, holder of the Viterbi Professorship of Engineering at USC, and the scientific and technical director of QCC.
At ISI we want to be at the forefront of new technologies, and to explore all the possibilities. We are excited to be pioneers in research on quantum computing, and to advance this field so that companies can harness the power of this emerging technology for themselves, said Craig Knoblock, Michael Keston executive director of ISI.
The Advantage system provides a four-fold increase in the number of qubits from our previous system as well as increased coherence and other performance metrics, Lidar said. We have great hopes for the new system as we explore coherent quantum annealing to achieve quantum speedups in quantum simulation, best-in-class optimization and machine learning. Some of our first projects will be to investigate speedup over classical optimization methods for hard optimization problems as well as pursuing additional government-funded research for identification and classification of quantum phase transitions.
Through QCC, USC is currently one of the first universities in the world to host and operate a commercial quantum computing system. The launch of the USC-Lockheed Martin Quantum Computing Center in 2011 was followed by similar investments by Google and NASA the following year.
Quantum Information Science (QIS) is a top priority research area for the nation and has long been a focus of USC Viterbi said Yannis C. Yortsos, dean of the USC Viterbi School of Engineering. In collaboration with Lockheed Martin, we established at ISI in 2011 the first academic home for a quantum computing system, namely D-Wave One.
USC faculty have mentored a new generation of Ph.D. students in QIS, who now have leadership positions in academia and the industry, Yortsos noted. The school has also established a new MS degree in QIS, with current worldwide student demand growing steadily.
For more than a decade, research and education in QIS at USC Viterbi has been thriving and constantly growing, Yortsos said.
The upgrade to Advantage offers multiple benefits for users. It will enable researchers to continue studying how quantum effects may speed up the solution of complex optimization, machine learning and sampling problems, and new breakthrough results in quantum optimization.
Businesses will benefit from the commercial use-cases that can be run on the quantum hybrid solver service. Government agencies and researchers also will have access to one of the most advanced systems in the United States for tackling key public sector initiatives including electrical grid resilience, emergency response and infrastructure optimization projects.
As a part of the D-Wave Leap quantum cloud service, users will immediately be able to access the Advantage quantum computer located at USC in real-time. Leap access gives researchers, government agencies and enterprises access to all of the programming tools and hybrid quantum-classical resources offered through Leap. This system will also be available today for use in Amazon Braket, Amazons quantum computing service.
To date, D-Waves customers have developed hundreds of early quantum applications in an array of fields such as financial modeling, flight planning, quantum chemistry simulation, automotive engineering, health care, logistics and more.
Making quantum computing ubiquitous and available is one of our core areas of focus and is central to the commercialization of quantum computing, said Alan Baratz, CEO of D-Wave. This is an important moment for our U.S.-based customers who want their Leap cloud access to the newest Advantage system and quantum hybrid solver service to be in region.
Eleven years ago, together with Lockheed Martin, we installed our first quantum system at USC, Baratz added. Fast forward to today, delivering one of the most performant commercial quantum computers in the world yet again allows users to harness the power of annealing quantum computing for real-world optimization problems, all accessible real-time through our Leap quantum cloud service and in AWSs Amazon Braket.

BT tests quantum radio receivers that could boost 5G coverage – TechRadar
BT is trialling a new hyper-sensitive quantum radio receiver that could boost the capabilities of 5G and Internet of Things (IoT) networks by reducing energy consumption and boosting coverage.
The receivers use excited atoms to achieve 100 times greater sensitivity than conventional radio equipment thanks to a quantum effect called electromagnetically induced transparency that forms a highly sensitive electric field detector.
Because the atomic radio frequency (RF) receivers are more sensitive, they could be deployed in areas where its impractical or not cost-effective to deploy mobile infrastructure. This would make nationwide 5G coverage a reality.
Meanwhile lower energy consumption would transform the economics of massive IoT projects that rely on long battery life.
The longer an IoT device can be left in the field without needing to be touched or replaced, the greater the return on investment.
BTs engineers successfully sent digitally-encoded messages using the technology via EEs 3.6GHz spectrum. The use of commercially-licensed frequencies could accelerate the timetable for the receivers to be used in the real world. Researchers are now working to miniaturise the equipment and find the optimum frequency modulation and signal processing so it can be used in the future.
BTs investment in cutting edge R&D plays a central role in ensuring the UK remains a network technology leader, said Howard Watson, BT chief technology officer (CTO). Our programme has huge potential to boost the performance of our next generation EE network and deliver an even better service to our customers. Although its early days for the technology, were proud to be playing an instrumental role in developing cutting edge science.
BTs interest in quantum technology has seen it and Toshiba build the worlds first commercial quantum-secured metro network using standard fibre cables in London.
The UK government has expressed a desire to be at the forefront of the field, believing quantum computing can play a vital role in the connected economy and accelerate Industrial Internet of things (IIoT) deployments. A National Quantum Computing Centre (NQCC) is expected to open in 2022 as part of the 1 billion National Quantum Technologies Programme.

Dynamics of Complex Quantum Systems and the Flight of the Bee – SciTechDaily
Levy flights describe statistical properties of elementary quantum magnets as well as of bees foraging for food. Credit: Christoph Hohmann (MCQST Cluster)
At first glance, a system consisting of 51 ions may appear to be easily manageable. But even if these charged atoms are only switched back and forth between two states, the result is more than two quadrillion (1015) different orderings which the system can take on.
The behavior of such a system is practically impossible to calculate with conventional computers, especially since an excitation introduced to the system can propagate erratically. The excitation follows a statistical pattern known as a Lvy Flight.
One characteristic of such movements is that, in addition to the smaller jumps which are to be expected, significantly larger jumps also sometimes take place. This phenomenon can also be observed in the flights of bees and in unusual fierce movements in the stock market.
While simulating the dynamics of a complex quantum system is a very tall order for even traditional super computers, the task is childs play for quantum simulators. But how can the results of a quantum simulator be verified without the ability to perform the same calculations it can?
Observation of quantum systems indicated that it might be possible to represent at least the long-term behavior of such systems with equations like the ones the Bernoulli brothers developed in the 18th century to describe the behavior of fluids.
In order to test this hypothesis, the authors used a quantum system which simulates the dynamics of quantum magnets. They were able to use it to prove that, after an initial phase dominated by quantum-mechanical effects, the system could actually be described with equations of the type familiar from fluid dynamics.
Furthermore, they showed that the same Lvy Flight statistics which describe the search strategies used by bees also apply to fluid-dynamic processes in quantum systems.
The quantum simulator was built at the Institute for Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences at The University of Innsbruck Campus. Our system effectively simulates a quantum magnet by representing the north and south poles of a molecular magnet using two energy levels of the ions, says IQOQI Innsbruck scientist Manoj Joshi.
Our greatest technical advance was the fact that we succeeded in individually addressing each one of the 51 ions individually, observes Manoj Joshi. As a result we were able to investigate the dynamics of any desired number of initial states, which was necessary in order to illustrate the emergence of the fluid dynamics.
While the number of qubits and the stability of the quantum states is currently very limited, there are questions for which we can already use the enormous computing power of quantum simulators today, says Michael Knap, Professor for Collective Quantum Dynamics at the Technical University of Munich.
In the near future, quantum simulators and quantum computers will be ideal platforms for researching the dynamics of complex quantum systems, explains Michael Knap. Now we know that after a certain point in time these systems follow the laws of classic fluid dynamics. Any strong deviations from that are an indication that the simulator isnt working properly.

Pentagon Leaders Get Briefed on Innovative Duke Research – Duke Today
A team from the U.S. military that included Gabriel Camarillo, under secretary of the Army, learned how shrimp, ants and quantum computing could improve military operations and technology during a tour of three Duke University research labs Monday.
Camarillo spent the afternoon getting briefed by Duke faculty members leading projects funded by the Army and other government agencies.
This research is absolutely critical to making the technological advances to develop war-fighting into the future, Camarillo said at the conclusion of his visit.
Jenny Lodge, Dukes vice president for research and innovation, said the tour highlighted the importance of Dukes partnerships with the Army and other agencies who see real-world applications in the science practiced every day in campus labs.
We dont want our research to just sit on shelves, Lodge said. We want it out in the world. These partnerships enable those translations to real-world uses.
Camarillos tour included stops in:
Its really hard to visualize the progress teams are making and potential future applications until you see the work, Camarillo said. Its also a chance to interact with the researchers and understand what the applications might be.
The visit Monday was the latest in a string of partnerships between Duke and the U.S. Army.
Last year, Duke entered an agreement with the Armys 18th Airborne Corps, based at Fort Bragg, N.C. to spur innovation by bringing military situations into the university research lab.
That partnership created Soldier-Academic Innovation Teams to collaborate on problems of interest to both the Army and Duke researchers. The agreement similar to those the Army has with other universities is intended to spur innovation in the military and increase research and learning opportunities at Duke.
That agreement, in turn, built on Army-Duke collaborations already underway, where Duke scholars helped develop solutions to real-world problems faced by the military.
In one exercise, for example, Duke students worked with officials at Seymour Johnson Air Force Base in Goldsboro streamline the planning and logistics of reservist training weekends through the design of software programs.
Camarillos visit to Duke also included a visit with recently retired mens basketball coach Mike Krzyzewski. Camarillo presented a statue to Krzyzewski a graduate of the U.S. Military Academy who also coached the Army basketball team for five seasons prior to taking over the Duke program in 1980

NFT Artist Refik Anadols First Supporters Were in the Tech World. All of a Sudden, Hes Become a Star at Auction, Too – artnet News
In 2006, the British mathematician Clive Humby famously proclaimed that data is the new oil.Little did he know it would also become the new art.
As one of the foremost practitioners of what he calls data painting, the Turkish American artist and TED Fellow Refik Anadol has been using data as the substance of his work for the better part of a decade. Over that time, hes won awardslike Lumen Prize and been featured at Venice Architecture Biennale and in shows at the National Gallery of Victoria and the Museum of Modern Art in New York.
I have always been interested in painting with data, Anadol told Artnet News from Barcelona last weekend, where he was on site to create a new digital artwork for the facade of Antoni Gauds iconic Casa Batll. Thousands of onlookers crowded the outside square towatch the illumination in an event organized by theOFFF Festival. The work was already traded as an NFT through Christies last week, when it sold for$1.38 million(and came with a dinner for 10).

For me, NFTs and digital art should be experiential. Landmarks have become my canvas, Anadol said. Im interested in exploring the architectural domain as deeply as I can. All my art works tend to have a physical connection to public space.
Using AI to regeneratively map iconic public buildings, Anadol works in equal parts architecture, graphic design, and computer science using a JavaScript object-based coding language called VVVV, which allows for live programming and projection mapping.
It was at UCLA that I learned about creative coding, he says, referring to his time in the schools media arts program. There, his advisors includedChristian Moeller, Casey Reas, and Jennifer Steinkamp.
In 2014, after graduating, he established the Refik Anadol Studio,which currently has a staff of 15 people. Our staff is multicultural and multilingual, Anadol said. We have an incredible staff of different minds and competencies.
Early in his career, Anadol focused on finding support from fellow technologists, rather than in the art world. Back when I first opened the studio in 2014, our earliest collaborators were not from the art or design worlds. They came from tech, he said.
In Quantum Memories, made when he was Googles artist-in-residence, he used the search giants publicly available quantum computing algorithms to 3D map the possibility of a parallel world. Part sci-fi, part next-level computer graphics, thealgorithm processed approximately 200 million images of nature to form an interactive algorithmic gesamtkunstwerk, mimicking the real-time simulations of audiences movements into an entangled web of generative world-building.

In another piece, Melting Memories (2018), inspired by his uncles Alzheimers diagnosis, Anadol transformed brain scans into projected images for the walls of the Pilevneli Gallery in Istanbul.The artwork and others also drew on Anadols longstanding interest in the imagery and history of space exploration.
To date,various iterations of the NFT have been auctioned via Nifty Gateway and Sothebys, with total sales of the project now exceeding $13 million USD, according to CryptoArt.io.Im extremely grateful to the NFT community for supporting my work, he said. The NFT world has given my studio economic independence.
(Asked what he has done with his wealth,Anadol says that whatever he doesnt reinvest into his studio goes to charity. OneNFT from a collection titled An Important Memory for Humanityraised $1.5 million for St Jude Childrens Hospital.)
Seoul Light, DDP, Seoul, KR, Courtesy RAS
In my art practice, I often ask myself the question: how would a computer collaborate with us to make art that not only is futuristic, but also about the possibility of various futures? he said. I do think that we approach answering this question only when we combine research efforts in various fields, including neuroscience, architecture, quantum computing, material science, philosophy, and arts.
Anadol is now busily preparing for two new works: one for an exhibition at Palazzo Strozzi that reimagines Italian Renaissance artworks; the other, a new piece to be shown in Istanbul and based on the writings of the13th-century Persian poet Rumi.For the latter work, Anadol will construct a digital installation in the foyer of the recently redesigned AKM Theater in Taksim Square.
All of us are standing on the shoulders of giants, Anadol said. Im just trying to explore the language of humanity.

IBM promises a 4,000+ qubit quantum computer by 2025: Here’s what it means – ZDNet
Two years after unveiling its quantum roadmap, IBM is keeping pace with its goals, the company said Tuesday -- and it has new plans to deliver a 4,000+ qubit quantum computer by 2025. That progress will move quantum computing beyond the experimentation phase by 2025, IBM CEO Arvind Krishna said this week to reporters.
For some simple use cases, organizations should be able to deploy quantum computers "in the 2023 to 2025 time frame," Krishna said ahead of the annual IBM Think conference in Boston. That means he explained, that electric vehicle makers could use quantum computers to analyze materials like lithium hydride to develop better batteries, or they could analyze allows for lighter weight but stronger vehicles. Other companies, meanwhile, could use quantum for simple optimization use cases, like optimizing search engines.
"As we begin to get to 4,000 qubits, a lot of these problems become within reach of quantum computers," Krishna said.
Meanwhile, the CEO said more complex quantum computing problems could be solved a few years later. Pharmaceutical companies, for instance, could see advantages by 2025 or 2030, he said.
"If you think about pharmaceutical drugs... that's probably going to be a little bit later," he said, adding that IBM is in "deep discussion with a few of those biotech companies."
"Covid vaccines have taught many of them that computation, as applied to medicine, can make things happen a lot quicker," Krishna continued. "They've all woken up to what computation can achieve. You can imagine some of them might be thinking a bit further to say, 'What can we do with quantum?'"
Back in 2020, IBM said it would deliver a 1,121-qubit device in 2023, as well as components and cooling systems. The company also released images of a 6-foot wide and 12-foot high cooling system being built to house a 1,121-qubit processor called IBM Quantum Condor. According to IBM, the goal is to build a million-qubit quantum system. The company said it views the 1,000-qubit mark as a tipping point to overcome the hurdles limiting the commercialization of quantum systems.
While building Condor, IBM last year announced Eagle, a 127-qubit processor. Later this year, IBM expects to unveil its 433-qubit processor called Osprey.
"To get to 4,000 [qubits], there's quite a few problems we have to solve," Krishna said. "How do you begin to scale these systems? How do you communicate amongst them? How do you get the software to scale and work from a cloud into these computers? These are all the problems we believe we have a line of sight to... so we have high confidence in our 2025 timeline."
In addition to working on physical quantum computers, IBM in 2023 will continue to improve development with Qiskit Runtime, its open source software that allows users to interact with quantum computers. It's also building workflows right into the cloud to a serverless approach into IBM's core quantum software stack.
Krishna said IBM is likely to be "open to all of the approaches" to delivering quantum computing, including selling it as a machine, delivering it as a managed service to customers, or delivering it as an on-premise service.

Quantum Computing Needs a Balance of Order and Disorder – Technology Networks
Research conducted within the Cluster of Excellence Matter and Light for Quantum Computing (ML4Q) has analysed cutting-edge device structures of quantum computers to demonstrate that some of them are indeed operating dangerously close to a threshold of chaotic meltdown. The challenge is to walk a thin line between too high, but also too low disorder to safeguard device operation. The study Transmon platform for quantum computing challenged by chaotic fluctuations has been published today inNature Communications.
In the race for what may become a key future technology, tech giants like IBM and Google are investing enormous resources into the development of quantum computing hardware. However, current platforms are not yet ready for practical applications. There remain multiple challenges, among them the control of device imperfections (disorder).
Its an old stability precaution: When large groups of people cross bridges, they need to avoid marching in step to prevent the formation of resonances destabilizing the construction. Perhaps counterintuitively, the superconducting transmon qubit processor a technologically advanced platform for quantum computing favoured by IBM, Google, and other consortia relies on the same principle: intentionally introduced disorder blocks the formation of resonant chaotic fluctuations, thus becoming an essential part of the production of multi-qubit processors.
To understand this seemingly paradoxical point, one should think of a transmon qubit as a kind of pendulum. Qubits interlinked to form a computing structure define a system of coupled pendulums a system that, like classical pendulums, can easily be excited to uncontrollably large oscillations with disastrous consequences. In the quantum world, such uncontrollable oscillations lead to the destruction of quantum information; the computer becomes unusable. Intentionally introduced local detunings of single pendulums keep such phenomena at bay.
The transmon chip not only tolerates but actually requires effectively random qubit-to-qubit device imperfections, explained Christoph Berke, final-year doctoral student in the group of Simon Trebst at the University of Cologne and first author of the paper. In our study, we ask just how reliable the stability by randomness principle is in practice. By applying state-of-the-art diagnostics of the theory of disordered systems, we were able to find that at least some of the industrially pursued system architectures are dangerously close to instability.
From the point of view of fundamental quantum physics, a transmon processor is a many-body quantum system with quantized energy levels. State-of-the-art numerical tools allow one to compute these discrete levels as a function of relevant system parameters, to obtain patterns superficially resembling a tangle of cooked spaghetti. A careful analysis of such structures for realistically modelled Google and IBM chips was one out of several diagnostic tools applied in the paper to map out a stability diagram for transmon quantum computing.
When we compared the Google to the IBM chips, we found that in the latter case qubit states may be coupled to a degree that controlled gate operations may be compromised, said Simon Trebst, head of the Computational Condensed Matter Physics group at the University of Cologne. In order to secure controlled gate operations, one thus needs to strike the subtle balance between stabilizing qubit integrity and enabling inter-qubit coupling. In the parlance of pasta preparation, one needs to prepare the quantum computer processor into perfection, keeping the energy states al dente and avoiding their tangling by overcooking.
The study of disorder in transmon hardware was performed as part of the Cluster of Excellence ML4Q in a collaborative work among the research groups of Simon Trebst and Alexander Altland at the University of Cologne and the group of David DiVincenzo at RWTH Aachen University and Forschungszentrum Jlich. This collaborative project is quite unique, says Alexander Altland from the Institute for Theoretical Physics in Cologne. Our complementary knowledge of transmon hardware, numerical simulation of complex many-body systems, and quantum chaos was the perfect prerequisite to understand how quantum information with disorder can be protected. It also indicates how insights obtained for small reference systems can be transferred to application-relevant design scales.
David DiVincenzo, founding director of the JARA-Institute for Quantum Information at RWTH Aachen University, draws the following conclusion: Our study demonstrates how important it is for hardware developers to combine device modelling with state-of-the-art quantum randomness methodology and to integrate chaos diagnostics as a routine part of qubit processor design in the superconducting platform.

The digital device you are using to view this article is no doubt using the bit, which can either be 0 or 1, as its basic unit of information. However, scientists around the world are racing to develop a new kind of computer based on the use of quantum bits, or qubits, which can simultaneously be 0 and 1 and could one day solve complex problems beyond any classical supercomputers.
A research team led by scientists at the U.S. Department of Energys (DOE) Argonne National Laboratory, in close collaboration with FAMU-FSU College of Engineering Associate Professor of Mechanical Engineering Wei Guo, has announced the creation of a new qubit platform that shows great promise to be developed into future quantum computers. Their work is published in the journal Nature.
Quantum computers could be a revolutionary tool for performing calculations that are practically impossible for classical computers, but there is still work to do to make them reality, said Guo, a paper co-author. With this research, we think we have a breakthrough that goes a long way toward making qubits that help realize this technologys potential.

While there are many choices of qubit types, the team chose the simplest one a single electron. Heating up a simple light filament such as you might find in a childs toy can easily shoot out a boundless supply of electrons.
One important quality for qubits is their ability to remain in a simultaneous 0 or 1 state for a long time, known as its coherence time. That time is limited, and the limit is determined by the way qubits interact with their environment. Defects in the qubit system can significantly reduce the coherence time.
For that reason, the team chose to trap an electron on an ultrapure solid neon surface in a vacuum. Neon is one of only six inert elements, meaning it does not react with other elements.
Because of this inertness, solid neon can serve as the cleanest possible solid in a vacuum to host and protect any qubits from being disrupted, said Dafei Jin, an Argonne scientist and the principal investigator of the project.
By using a chip-scale superconducting resonator like a miniature microwave oven the team was able to manipulate the trapped electrons, allowing them to read and store information from the qubit, thus making it useful for use in future quantum computers.
Previous research used liquid helium as the medium for holding electrons. That material was easy to make free of defects, but vibrations of the liquid-free surface could easily disturb the electron state and hence compromise the performance of the qubit.
Solid neon offers a material with few defects that doesnt vibrate like liquid helium. After building their platform, the team performed real-time qubit operations using microwave photons on a trapped electron and characterized its quantum properties. These tests demonstrated that solid neon provided a robust environment for the electron with very low electric noise to disturb it. Most importantly, the qubit attained coherence times in the quantum state competitive with other state-of-the-art qubits.
The simplicity of the qubit platform should also lend itself to simple, low-cost manufacturing, Jin said.
The promise of quantum computing lies in the ability of this next-generation technology to calculate certain problems much faster than classical computers. Researchers aim to combine long coherence times with the ability of multiple qubits to link together known as entanglement. Quantum computers thereby could find the answers to problems that would take a classical computer many years to resolve.
Consider a problem where researchers want to find the lowest energy configuration of a protein made of many amino acids. These amino acids can fold in trillions of ways that no classical computer has the memory to handle. With quantum computing, one can use entangled qubits to create a superposition of all folding configurations providing the ability to check all possible answers at the same time and solve the problem more efficiently.
Researchers would just need to do one calculation, instead of trying trillions of possible configurations, Guo said.
