Quantum Market, Though Small, will Grow 22% and Hit $1.5B in 2026 – HPCwire

Few markets as small as the quantum information sciences market generate as much lively discussion. Hyperion Research pegged the worldwide quantum market at $848 million for 2023 and expects it to reach ~$1.5 billion in 2026, according to its annual quantum computing (QC) market update presented at the Q2B Silicon Valley conference held in Santa Clara this week.

Bob Sorensen, Hyperion Researchs chief quantum analyst who presented the market update, told HPCwire, I think that a positive, if not robust, market projection is justified.The QC ecosystem is becoming more sophisticated and granular with increased opportunities from QC processor suppliers, targeted classical control system vendors, QC systems integrators, software orchestration firms, and a growing base of sector-specific QC applications developers. All that adds up to a more finely-tuned QC solution well suited to the particular requirements for any potential QC end user, making quantum computing a more attractive compute option going forward.

It is sobering that there are so many uncertainties remaining in QC writ large, ranging from figuring out what will be the quantum transistor (e.g. preferred qubit modality), to implementing needed error correction and scaling up system size, and ultimately building a library of quantum algorithms and applications to fulfill quantum computings tantalizing promise.

Whats not uncertain is the global race among quantum believers, including governments, companies, and academia all chasing the goal. For example, the U.S. is expected to reauthorize the National Quantum Initiative Act for a second five years sometime this month. Consider the major international organizations that assisted Hyperion in conducting its most recent QC market survey:

Having missed out on the semiconductor revolution the underpinning of the modern electronics industry many regions (small and large) are jumping in so as not to miss the quantum revolution. For the moment, the quantum computing ecosystem retains its roughly bi-modal nature, with a few giants and very many smaller companies jostling for sway.

As shown below, the make-up of Hyperion survey is a broad reflection on the QC market. Twenty-four respondent companies had total (not just quantum) revenues of more than $10 billion and 39 had less than $15 million. Only two companies reported more than $50 million in quantum revenue. The long (irregular) tail of 66 companies with under $1 million is more broadly representative of the aspiring QC market.

A relative newcomer to the Hyperion outlook is a more bullish attitude towards deployment of on-premise quantum systems. Both IBM and D-Wave have deployed their systems at user facilities in the past, but no others. Just this year, both QuEra (neutral atom-based qubits) and IonQ (trapped ion qubits) have announced plans to offer on-premise systems, and HPCwire has talked with at least one quantum industry veteran whos planning a quantum integrator business model to assist in deploying and integrating quantum systems into datacenters.

Sorensen said, The positive future of QC installations on-premises is clear, at least to me.Despite many of the current advantages to QC access via cloud (pay as you go options, the ability to switch qubit modalities and vendors easily, andthe relatively low capex requirements during the exploratory phase) there will be an increasing interest by QC end users firms that will have any number of reasons to use an on-prem QC, including the need to protect proprietary information, speed tightly integrated hybrid quantum/classical algorithms, ensure24/7 access to a specific machine, and likely in cases where QC usage is high, secure a lower costset-up than a cloud access alternative.

In addition, many HPC sites are and will be looking to bolster in-house QC expertise and having a system on site offers more opportunity to do that versus a cloud-based option. That said, issues to be ironed out include buy versus lease, especially at a time when hardware advances are happening quickly, decisions about which quantum modality, architecture, and vendor to commit to, and the ability to effectively integrate an on-premises QCinto an existing classical HPC ecosystem, he said.

In keeping with past studies, the top targeted sectors remain steady, although the FS sector dropped from the top spot. Prospective QC end-user attitudes about demand drivers are interesting in that they reflect, for example, the growing recognition that the traditional HPC hardware paradigm is stuck. All netted out, QC user budget expectations are also up.

On balance, Sorensens view of QC prospects is positive.

The QC sector currently is marked by a wide range of innovation with many questions about which quantum hardware and software will eventually reign supreme, he said.However, a sure sign of viable technology, especially one that could drastically redefine something as far reachingand entrenched as the classical IT sector, is that exploration is taking place across the academic, government, and the vast array of commercial entities.

All this does is ensure that every considered quantum option will have its opportunity to shine, but only if it can prove its merits. There will be a range of companies that enter the market, with some departing, some being consolidated, or some pivoting to new opportunities. But as long as the overall scope of innovation stayson an upward trajectory, future prospects for the QC sector are good.

A new consideration is the emergence of LLMs and concern regarding what impact it will have on efforts and funds flowing into the quantum ecosystem. At the moment, the quantum community doesnt seem overly worried. It should also be noted that there are many efforts to harness LLMs as education tools for quantum computing as well as as coding aids to enable developers to write code for quantum computers without having to master quantum specific tools. Jay Gambetta, VP IBM Quantum, told HPCwire recently, We [think] the full power of using quantum computing will be powered by generative AI to simplify the developer experience.

As with all things quantum computing, a measure of caution is smart Hyperion, for example, couched its outlook as estimates rather than firm forecasts. There are still a lot moving pieces in the gradually coalescing quantum landscape puzzle.

IBM has unveiled the first quantum computer with 1,121 superconducting qubits (qubits are the quantum equivalent of digital bits in a classical computer). Quantum computers could outperform classical computers in certain areas by exploiting phenomena such as entanglement and superposition. However, these quantum states are notoriously fickle and prone to error, so simply having more qubits does not necessarily make a system better. IBM says it will now focus on more error-resistant systems, rather than larger ones.

The discovery of the earliest known fossil mosquitoes, preserved in Lebanese amber, had a sting in the tail: the insects were bloodsucking males. Today, only female mosquitoes eat blood, with males living on nectar and plant juices. The 125-million-year-old fossils have mouthparts that look perfect for piercing skin, as well as mate-grabbing appendages that confirm their sex. The finding could turn current thinking that blood-sucking evolved after plant-eating on its head. We think now that, originally, the mosquito could be bloodsucking, says palaeontologist and study co-author Dany Azar. With the appearance of the flowering plant, this function could be just forgotten later on.

A new attempt to reconcile the physics of the very big and very small offers up a testable prediction: time itself might be wobbly. Physicists have long sought a unifying theory that integrates the spectacularly successful but mathematically incompatible general theory of relativity and quantum theory. The postquantum theory of classical gravity suggests that space-time is smooth and continuous, not quantized into discrete chunks. But it has fluctuations which could be revealed by precise table-top mass measurements. Its quite mathematical, admits physicist Jonathan Oppenheim. Picturing it in your head is quite difficult.

Studies have suggested that fruits and vegetables contain lower levels of micronutrients such as iron, vitamins and zinc than they used to. It can be hard to know whether the effect is real, however, because most studies use historical data and compare different crop varieties, levels of ripeness, soil types and farming methods. But for some crops, such as wheat, the evidence is clear: the introduction of high-yielding varieties in the 1960s led to a nutritional decline. When plants produce more carbohydrates, this dilutes other grain components, including micronutrients. And the same mechanism seems to apply when plants respond to increasing levels of carbon dioxide in the atmosphere.

Quantum entanglement of individual molecules achieved by physicists for the first time – Innovation News Network

Individual molecules have been forced into special states of quantum entanglement where they can remain correlated with each other, even if they occupy opposite ends of the Universe.

This is a breakthrough in the world of molecules because of the fundamental importance of quantum entanglement, said Lawrence Cheuk, assistant professor of physics at Princeton University and the senior author of the paper.

But it is also a breakthrough for practical applications because entangled molecules can be the building blocks for many future applications.

The research, On-Demand Entanglement of Molecules in a Reconfigurable Optical Tweezer Array, was recently published in the journal Science.

Applications of molecules that have gone through quantum entanglement include quantum computers that can solve certain problems faster than conventional computers.

The molecules can also be used for quantum simulators that can model complex materials whose behaviours are difficult to model, and quantum sensors that can measure faster than their traditional counterparts.

Connor Holland, a graduate student in the physics department and a co-author of the work, said: One of the motivations in doing quantum science is that in the practical world, it turns out that if you harness the laws of quantum mechanics, you can do a lot better in many areas.

The quantum advantage is the ability of quantum devices to outperform classical ones. At the core of quantum advantage are the principles of superposition and quantum entanglement.

A classical computer can assume the value of either 0 or 1, whilst qubits can be in a superposition of 0 and 1.

Quantum entanglement is a major cornerstone of quantum mechanics and occurs when two particles become so linked that it persists even if one particle is lightyears away from the other.

Entanglement is an accurate description of the physical world and how reality is structured.

Quantum entanglement is a fundamental concept, said Cheuk, but it is also the key ingredient that bestows quantum advantage.

Building quantum advantage and achieving controllable quantum entanglement is challenging as scientists are unclear as to which physical platform is best for creating qubits.

Previously, many different technologies have been explored as candidates for quantum computers and devices. The optimal quantum system could depend on the specific application.

However, molecules have long defied controllable quantum entanglement until now.

The Princeton University team manipulated individual molecules to control and coax them into interlocking quantum states. They believe that molecules have advantages over atoms that make them better suited for certain applications in quantum information processing and simulation of complex materials.

Compared to atoms, molecules have more quantum degrees of freedom and can interact in new ways.

What this means, in practical terms, is that there are new ways of storing and processing quantum information, said Yukai Lu, a graduate student in electrical and computer engineering and a co-author of the paper.

For example, a molecule can vibrate and rotate in multiple modes. So, you can use two of these modes to encode a qubit. If the molecular species is polar, two molecules can interact even when spatially separated.

However, despite their advantages, molecules are hard to control in the laboratory because they are complex. Their attractive degrees of freedom also make them hard to control in laboratory settings.

First, the team picked a molecular species that is both polar and can be cooled with lasers. The molecules were cooled to ultracold temperatures where quantum mechanics can occur. Individual molecules were then picked up by a complex system of focused laser beams called optical tweezers.

Through the engineering of these tweezers, the team created large arrays of single molecules to position them in a one-dimensional configuration.

They then encoded a qubit into a non-rotating and rotating state of the molecule. This molecular qubit was shown to remain coherent remembering its superposition. Thus, the team revealed that they could create well-controlled and coherent qubits out of individually controlled molecules.

To enable molecular quantum entanglement, the team ensured that the molecules could interact using a series of microwave pulses. By allowing this interaction for a precise amount of time, the team could implement a two-qubit gate that entangled two molecules. This is important because such an entangling two-qubit gate is a building block for universal quantum computing and the simulation of complex materials.

The research will help to investigate different areas of quantum science. The team is particularly interested in exploring the physics of interacting molecules which can be used to simulate quantum many-body systems where interesting emergent behaviour like new forms of magnetism can appear.

Cheuk said: Using molecules for quantum science is a new frontier and our demonstration of on-demand entanglement is a key step in demonstrating that molecules can be used as a viable platform for quantum science.

In a separate article published in the journal Science, an independent research group reported the achievement of similar results.

Cheuk concluded: The fact that they got the same results verify the reliability of our results.

They also show that molecular tweezer arrays are becoming an exciting new platform for quantum science.

Three-Year, $2.5 Million DOE Grant Puts Chico State at Leading Edge of Teaching Quantum Computing – California State University, Chico

Jason Halley / University Photographer

Quantum computing has piqued the interest of physicists, mathematicians and computer scientists with its potential to solve some of the worlds most complex problems faster and more accurately than ever. A grant from the US Department of Energy (DOE) puts Chico State and collaborators from CSU San Marcos at the CSUs leading edge in preparing students for a quantum computing future.

In efforts to promote the field of quantum information science and technology (QIST)an area of science that impacts communication, quantum computing and sensingChico State Department of Computer Science Associate Professor Jaime Raigoza and other scientists from around the state have been awarded a three-year, $2.5 million grant from the DOE.

Funding for the grant titled QIST in the CSU: Expanding Access to Quantum Information Science and Technology was awarded to Chico State and co-Principal Investigator Raigoza, CSU San Marcos Physics Professor and PI Justin Perron, the CSU Chancellors Office, Sandia National Laboratories and Growth Sector, a Bay Area nonprofit that works with community colleges to expand access to STEM degrees and careers.

The grant, which began in February 2023 and will run through February 2026, brings QIST to the CSU by funding faculty workshops and online learning communities; curriculum dissemination through STEM-NETthe CSU multicampus consortia at the Chancellors Officesummer quantum experience camps; year-long quantum-focus student learning communities at both Chico State and San Marcos; and student internships at Sandia National Laboratories.

Raigoza notes that the practical possibilities for quantum computing are broad and potentially impactful on everyday life.

Some practical applications of this emerging technology include secure communication, the simulation of more complex molecules in discovering new drugs, developing tools to provide early cancer detection and an impact on the energy sector to provide a more efficient infrastructure, Raigoza said. The potential to solve complex problems plus the impact on national security also exists.

The purpose of the project is twofold. The first is a focus on providing opportunities and support to students with bridge programs to introduce incoming undergraduate students to QIST and ensure they have the necessary math skills to succeed in their majors. Additionally, cohort-based learning communities will provide professional development opportunities for students, and coveted summer internships at Sandia National Laboratories for undergraduate students will offer valuable QIST research experiences.

This robust list of experiential research will educate and empower undergraduate students to fill a much-anticipated workforce in the futurewith that happening right here in the CSU.

With the field being so new, there currently are insufficient education and workforce development opportunities at the undergraduate level to meet the anticipated need, Perron said. This project hopes to help address this by building capacity in the CSU and leveraging existing resources to help bring the field to our diverse student population.

The second purpose is to focus on faculty activities to expand the capacity within the CSU to offer QIST courses, research and support.

QIST has the potential to revolutionize the computing field. To meet the growing quantum computing workforce, students will need to understand this new field where very few schools are teaching, especially within the CSU, Raigoza said.

Riverlane Partners with Infleqtion and Nv Cameras to Help Quantum Computers ‘See’ Their Qubits – AZoOptics

A new project will bring together leading UK and Canadian companies to develop the imaging systems to measure qubit states. This is a vital capability for quantum computers to scale.

Quantum computers are based on building blocks called qubits (quantum bits), but they are not yet powerful enough to unlock any real-world applications. To achieve this, the number and quality of qubits must grow, together with the optical and electronic systems needed to perform operations with qubits and read out the results.

Steve Brierley, CEO and Founder at Riverlane, said: "We need to reach the scale where quantum computers can perform roughly a trillion reliable quantum operations a threshold we call the 'TeraQuop'. Todays quantum computers are only capable of a few hundred error-free operations. This project pushes us closer to this TeraQuop goal, but we cannot do this alone and this is why collaboration with leaders likeInfleqtion andNv Camras is vital, enabling the continued, long-term growth of quantum computing."

In the Scalable Qubit Array Detection for Rydberg Quantum Computers project, quantum computing companies Infleqtion and Riverlane will collaborate with imaging systems specialists Nv Camras to develop systems to greatly improve the readout of the status of the qubits.

The partnership between Infleqtion,Nv Camrasand Riverlane will allow for collaborative development in this area of the quantum computing supply chain, helpingNv Camrasto develop cameras targeting the next generation of quantum computers, Riverlane to equip its quantum control systems with advanced readout capabilities and Infleqtion to validate the necessary hardware control layer.

There are many qubit types. This project focuses on the neutral atom qubits that Infleqtion's quantum computing platform uses. Accurate knowledge of the state of these atoms is crucial for the quantum computer to perform its operations. This requires high detection sensitivity, accurate measurements, and low latency to enable real-time image processing and faster operations.

Marie-Eve Ducharme, President and Co-Founder at Nv Camras, said: "Weve been pioneering projects in the space sector for over a decade, but demand for our unique imaging capabilities is exploding in the quantum physics field. This project marks a new milestone for Nv Camras and showcases the transformative potential of our technology in accelerating quantum computing advancements. We are grateful for the contribution of the National Research Council of Canada (NRC-IRAP) to enable this work."

Dr Timothy Ballance, President of Infleqtion UK, said, "Neutral atom quantum computing holds great promise for practical quantum computing through the scalability of atomic qubits compared to alternative methodologies. To truly unlock this scalability, we will need to work hand-in-hand with hardware providers and integrators across the quantum stack to ensure that the sub-systems are interoperable. We are thrilled to collaborate with Riverlane and Nv Camras on this exciting project which will advance high-speed detection of large arrays of atomic qubits."

The project is funded jointly by Innovate UK and the NRC-IRAP through the Canada-UK Commercialising Quantum Technology Programme. Innovate UK is investing 4.2 million in 11 projects to strengthen collaborative research and development through Canada-UK partnerships.
