GlobalFoundries adapts silicon photonics for quantum computing

GlobalFoundries is now manufacturing the silicon photonic and electronic chips that form the foundation of PsiQuantum's Q1 quantum computer.

PsiQuantum, a start-up based in Palo Alto, California, aims to be the first to deliver a commercially viable quantum computer with one million qubits.

PsiQuantum and GF have now demonstrated the ability to manufacture core quantum components, such as single-photon sources and single-photon detectors, with precision and in volume, using the standard manufacturing processes of GF’s semiconductor fab. The companies have also installed proprietary production and manufacturing equipment in two of GF’s 300mm fabs to produce thousands of Q1 silicon photonic chips at its facility in upstate New York, and state-of-the-art electronic control chips at its Fab 1 facility in Dresden, Germany.

PsiQuantum’s Q1 system represents breakthroughs in silicon photonics, which the company believes is the only way to scale to 1 million-plus qubits and beyond and to deliver an error-corrected, fault-tolerant, general-purpose quantum computer.

“In the past year, we have experienced a decade of technological change. Now, due to the digital transformation and the explosion of data we are faced with problems that require quantum computing to further accelerate the Renaissance of Compute,” said Amir Faintuch, senior vice president and general manager of Compute and Wired Infrastructure at GF. “PsiQuantum and GF’s partnership is a powerful combination of PsiQuantum’s photonic quantum computing expertise and GF’s silicon photonics manufacturing capability that will transform industries and technology applications across climate, energy, healthcare, materials science, and government.”

“This is a major achievement for both the quantum and semiconductor industries, demonstrating that it’s possible to build the critical components of a quantum computer on a silicon chip, using the standard manufacturing processes of a world-leading semiconductor fab,” said Pete Shadbolt, chief strategy officer and co-founder of PsiQuantum. “When we first envisioned PsiQuantum, we knew that scaling the system would be the existential question. Together with GLOBALFOUNDRIES, we have validated the manufacturing path for silicon photonics and are confident that by the middle of this decade, PsiQuantum will have completely stood up all the manufacturing lines and processes necessary to begin assembling a final machine.”

NTT develops quantum random number generator

Researchers at NTT have developed a quantum random number generator (QRNG) that exploits the probabilistic nature of quantum measurements to generate genuine random numbers. 

The breakthrough could be implemented as a server that repeatedly produces fixed blocks of fresh, certifiable, public random bits. Applications might include communication networks with high security enhanced by quantum technologies.

NTT said previous high-performance QRNGs require fully characterized quantum devices, which could be subject to security loopholes. Although there are QRNGs that are secure with realistic devices, they need to run for a long time to accumulate sufficient randomness. This results in high latency from the initial request to the delivery of the requested random bits. It is desirable for real-world applications to realize QRNGs of low latency, high rate and high security. In this work, by developing an efficient method for certifying randomness (a collaborative work with the researchers at the National Institute of Standards and Technology) and by measuring the arrival time of an optical pulse with time-bin encoding, NTT was able toshow that every 0.1 seconds a block of 8192 quantum-safe random bits can be generated, enabling low-latency high-rate performance.

NTT Research and Caltech to develop coherent ising machine


NTT Research has signed a collaboration agreement with Caltech to develop a high-speed Coherent Ising Machine (CIM). 

A CIM is a network of optical parametric oscillators (OPOs) programmed to solve problems that have been mapped to an Ising model, which is a mathematical abstraction of magnetic systems composed of competitively interacting spins, or angular momentums of fundamental particles. The CIM is particularly suited to combinatorial optimization problems that are beyond the capabilities of current computer processors to solve. NTT Research and Caltech will jointly develop a high-speed, miniature CIM, consisting of an on-chip 100 GHz pulsed pump laser source and on-chip parametric oscillator device.

The principal investigator at Caltech for this four-and-a-half-year joint project is Kerry Vahala, the Jenkins Professor of Information Science and Technology and Applied Physics and Executive Officer for the department of Applied Physics and Materials Science. Professor Vahala has pioneered the use of nonlinear optics in high-Q optical micro-resonators. Leading this effort at NTT Research is PHI Lab Research Scientist, Dr. Myoung-Gyun Suh, an expert in on-chip optical sources and their application to precision measurements.

“We are delighted at the prospect of working with Professor Vahala to develop an extremely small and high-speed CIM,” said NTT Research PHI Lab Director, Yoshihisa Yamamoto. “This work will advance our understanding of the CIM’s capabilities, map well with ongoing and related work with other institutions, provide new demonstrations of this awesomely powerful new information system and, we hope, set standards for the CIM’s speed and size.”

To date, the NTT Research PHI Lab has established ten joint research projects as part of its long-range goal to radically redesign artificial computers, both classical and quantum. To advance that goal, the PHI Lab has established joint research agreements with seven universities, one government agency and quantum computing software company. This is the second joint research agreement with Caltech. The other institutions of higher education are Cornell University, Massachusetts Institute of Technology (MIT), Stanford University, Swinburne University of Technology, the University of Michigan and the University of Notre Dame. 

NTT Tackles Artificial Spin for Photonic Computation

Researchers at NTT and and Osaka University announced an important step toward photonic computation by developing a large-scale artificial spin network based on photonics technologies. The development targets a fundamental component for the coherent Ising machine (CIM), which utilizes interacting artificial spins realized with optical parametric oscillators (OPO) for computation of combinatorial optimization problems.

The researchers generated more than 10,000 time-multiplexed OPOs using an optical fiber cavity as long as 1 km.

The OPOs can be used as artificial spins for a large-scale CIM to solve combinatorial optimization problems in the real world. The research was published in the UK science journal “Nature Photonics” on April 18, 2006.

NTT researchers streamline quantum calculations with ZX-Calculus

Researchers at NTT are pursuing a novel method to reduce the resources associated with large-scale fault-tolerant quantum circuits by employing ZX-calculus.

Currently, a fault-tolerant quantum circuit for a given computation requires a huge amount of resources, both in terms of qubits and computational time. The researchers at NTT have found an efficient method to compress such circuits with the purpose of decreasing their hardware demands. They use ZX-Calculus as an intermediate language to reduce both the number of qubits and time required to perform such computation in many different circuits. 

A paper on the topic discusses an improvement of a 40% compression rate with respect to previous reductions, yielding compression rates higher than 70% compared to the initial circuit. The methodology proposed in this work promises to open new venues of research in large-scale quantum computing and bring quantum computation closer to reality by relaxing its hardware demands.

Verizon tests Quantum Key Distribution

Verizon set-up a trial Quantum Key Distribution (QKD) network in the Washington D.C. area.

Live video was captured outside of three Verizon locations in the D.C. area, including the Washington DC Executive Briefing Center, the 5G Lab in D.C and Verizon’s Ashburn, VA office. Using a QKD network, quantum keys were created and exchanged over a fiber network between Verizon locations. Video streams were encrypted and delivered more securely allowing the recipient to see the video in real-time while ensuring hackers are instantly detected.

A QKD network derives cryptographic keys using the quantum properties of photons to prevent against eavesdropping. Verizon also demonstrated that data can be further secured with keys generated using a Quantum Random Number Generator (QRNG) that creates truly random numbers that can’t be predicted. With QKD, encryption keys are continuously generated and are immune to attacks because any disruption to the channel breaks the quantum state of photons signaling
eavesdroppers are present.

"The use of quantum mechanics is a great step forward in data security,” said Christina Richmond, analyst at IDC. “Verizon's own tests, as well other industry testing, have shown that deriving "secret keys" between two entities via light photons effectively blocks perfect cloning by an eavesdropper if a key intercept is attempted. Current technological breakthroughs have proven that both the quantum channel and encrypted data channel can be sent over a single optical fiber. Verizon has demonstrated this streamlined approach brings greater efficiency for practical large-scale implementation allowing keys to be securely shared over wide-ranging networks.”

MIT advances quantum information sharing between processors

Researchers at MIT are developing an on-off system that leverages "giant atoms" to enable high-fidelity operations and interconnection between processors.

A key challenge in quantum computing has been to communicate quantum information between distant parts of a processor.

In a paper published in the journal Nature, the MIT researchers constructed “giant artificial atoms” from superconducting quantum bits, or qubits, connected in a tunable configuration to a microwave transmission line, or waveguide.

“Coupling a qubit to a waveguide is usually quite bad for qubit operations, since doing so can significantly reduce the lifetime of the qubit,” says Bharath Kannan, MIT graduate fellow and first author of the paper. “However, the waveguide is necessary in order to release and route quantum information throughout the processor. Here, we’ve shown that it’s possible to preserve the coherence of the qubit even though it’s strongly coupled to a waveguide. We then have the ability to determine when we want to release the information stored in the qubit. We have shown how giant atoms can be used to turn the interaction with the waveguide on and off.”

Blueprint for the Quantum Internet

The U.S. Department of Energy (DOE) outlined a blueprint strategy for the development of a national Quantum Internet.

The DoE's 17 national laboratories will serve as the first nodes on the Quantum Internet. Also participating will be the National Science Foundation, the Department of Defense, the National Institute for Standards and Technology, the National Security Agency, and NASA. The academic community and industry will also be invited.

At a launch event hosted by the University of Chicago, officals described the initiative as "bringing the United States to the forefront of the global quantum race and ushering in a new era of communications."

“The Department of Energy is proud to play an instrumental role in the development of the national quantum internet,” said U.S. Secretary of Energy Dan Brouillette. “By constructing this new and emerging technology, the United States continues with its commitment to maintain and expand our quantum capabilities.”

In February, scientists from DOE’s Argonne National Laboratory in Lemont, Illinois, and the University of Chicago entangled photons across a 52-mile “quantum loop” in the Chicago suburbs, successfully establishing one of the longest land-based quantum networks in the nation. That network will soon be connected to DOE’s Fermilab in Batavia, Illinois, establishing a three-node, 80-mile testbed.

“The combined intellectual and technological leadership of the University of Chicago, Argonne, and Fermilab has given Chicago a central role in the global competition to develop quantum information technologies,” said Robert J. Zimmer, president of the University of Chicago. “This work entails defining and building entirely new fields of study, and with them, new frontiers for technological applications that can improve the quality of life for many around the world and support the long-term competitiveness of our city, state, and nation.”

 “Argonne, Fermilab, and the University of Chicago have a long history of working together to accelerate technology that drives U.S. prosperity and security,” said Argonne Director Paul Kearns. “We continue that tradition by tackling the challenges of establishing a national quantum internet, expanding our collaboration to tap into the vast power of American scientists and engineers around the country.”

MIT's “Light squeezer” reduces quantum noise in lasers

Researchers at MIT have developed a quantum “light squeezer” that reduces quantum noise in an incoming laser beam by 15%.

The portable light squeezer works at room temperature and could be used to improve laser measurements where quantum noise is a limiting factor. The setup is based on a marble-sized optical cavity, housed in a vacuum chamber and containing two mirrors, the first of which is smaller than the diameter of a human hair. The second, larger, nanomechanical mirror, which suspended by a spring-like cantileve, is the key to the system’s ability to work at room temperature.

“The importance of the result is that you can engineer these mechanical systems so that at room temperature, they still can have quantum mechanical properties,” says Nergis Mavalvala, the Marble Professor and associate head of physics at MIT. “That changes the game completely in terms of being able to use these systems, not just in our own labs, housed in large cryogenic refrigerators, but out in the world.”

MIT: Scaling up the quantum chip

Researchers at MIT have achieved a breakthrough in the field of scalable quantum processors by developing a process to manufacture and integrate “artificial atoms,” created by atomic-scale defects in microscopically thin slices of diamond, with photonic circuitry.

A team, led by Dirk Englund, an associate professor in MIT’s Department of Electrical Engineering and Computer Science, were able to build a 128-qubit system — the largest integrated artificial atom-photonics chip to date. The hybrid manufacturing approach iused carefully selected “quantum micro chiplets” containing multiple diamond-based qubits placed on an aluminum nitride photonic integrated circuit.

“In the past 20 years of quantum engineering, it has been the ultimate vision to manufacture such artificial qubit systems at volumes comparable to integrated electronics,” Englund says. “Although there has been remarkable progress in this very active area of research, fabrication and materials complications have thus far yielded just two to three emitters per photonic system.”

Researchers test quantum entanglement from nanosatellite

Researchers from the National University of Singapore and NASA generated and detected quantum entanglement onboard a CubeSat nanosatellite orbiting the Earth.

The experiment demonstrated that a miniaturized source of quantum entanglement can operate successfully in space aboard a low-resource, cost-effective CubeSat that is smaller than a shoebox (10 cm × 10 cm × 10 cm).

The photon-pair source consisted of a blue laser diode that shines on nonlinear crystals to create pairs of photons. Achieving high-quality entanglement required a complete redesign of the mounts that align the nonlinear crystals with high precision and stability. The nanosatellite, named SpooQy-1, was deployed into orbit from the International Space Station on 17-June-2019. The instrument successfully generated entangled photon-pairs over temperatures from 16 °C to 21.5 °C.

“In the future, our system could be part of a global quantum network transmitting quantum signals to receivers on Earth or on other spacecraft,” said lead author Aitor Villar from the Centre for Quantum Technologies at the National University of Singapore. “These signals could be used to implement any type of quantum communications application, from quantum key distribution for extremely secure data transmission to quantum teleportation, where information is transferred by replicating the state of a quantum system from a distance.”

A report on the project was published in Optica, The Optical Society's (OSA) journal for high impact research.

The researchers are now working with RALSpace in the UK to design and build a quantum nanosatellite similar to SpooQy-1 with the capabilities needed to beam entangled photons from space to a ground receiver. This is slated for demonstration aboard a 2022 mission.

OIDA Quantum Photonics Roadmap: Every Photon Counts

A newly released Quantum Photonics Roadmap: Every Photon Counts, which was produced by OSA Industry Development Associates (OIDA) in collaboration with Corning, clarifies the applications and timing for quantum technologies and specifies improvements in optics and photonics components needed to enable commercialization. It covers the three major application areas: quantum sensing and metrology, quantum communications and quantum computing.

Commercialization of products such as quantum sensors for GPS-free navigation and field-deployable quantum repeaters for communications will be significant milestones in an emerging market but more investments in product engineering are critical. Lower SWAP-C devices would enable progress, for example, across multiple sensing categories, and integration of these systems onto photonic chips is a critical path to doing so. While some integration is possible today, more on-chip functionality (e.g., sources, modulators, switches) is needed.

“While the field still needs breakthroughs in quantum science, such as a quantum repeater, the photonics technology already largely exists for laboratory experiments,” says Tom Hausken, senior industry advisor, The Optical Society (OSA). “The product engineering -- low size, weight, power and cost -- is missing, or it is applied to a specific customer application, without benefit to the rest of the field. The need is analogous to the talent shortage, not just with scientists, but with engineers in photonics, microwave and control electronics, packaging and cryogenics who have the specialized expertise to bring the technology to market.”



Although the quantum technology market is still in the early stages, the optics and photonics community already supplies critical enabling components to research and development labs in the near term to ensure progress. OIDA estimates sales of optics and photonics for lab equipment used by quantum researchers at about US$100 million per year. The commercial market for quantum end-use products is expected to rise to billions of dollars by 2030.

“The real impact of quantum technology is what it can do, which could be far greater than the market for the technology itself,” Hausken adds. “The fear of missing out (FOMO) on that impact on competitiveness and security is driving funding in quantum research, which OIDA estimates at about US$2 billion annually.”

The public and private sectors worldwide are making multi-year investments in quantum technologies with an end-goal of market ready applications. In the U.S., the National Quantum Initiative Act, a multi-agency plan, proposes US$1.2 billion in funding for quantum information science over five-years. The European Union’s Quantum Flagship program is budgeted at 1 billion euros over a ten-year period.

Investments in the product engineering of quantum technology could support classical applications as well. For example, investments in lower loss integrated photonics and single-photon detectors could yield benefits in classical optical communications and low-light imaging, respectively. Integrated photonics offers many promising solutions for quantum technology, at a time when it offers multiple solutions in other fields.

SK Telecom shows 5G phone with quantum random number generator

SK Telecom, together with Samsung Electronics and ID Quantique, demonstrated the first 5G smartphone equipped with a quantum random number generator chipset.

The Samsung Galaxy A Quantum with integrated quantum-enhanced cryptography will allow customers to experience advanced security through two-factor authentication for T-ID, biometric authentication-based payment for SK Pay and mobile e-certification service.

“Securing mobiles phones has become a top priority for mobile operators, who are also looking to generate new revenues,” Says Grégoire Ribordy, co-founder and CEO of ID Quantique. “With its compact size and low power consumption, our latest Quantis QRNG chip can be embedded in any smartphone, to ensure trusted authentication and encryption of sensitive information. It will bring a new level of security to the mobile phone industry.”

  • Last year, SK Telecom and ID Quantique were awarded quantum communication network-building projects in the U.S. and Europe (EU), and applied QRNG to SK Telecom’s 5G authentication center (AuC) for the first time in the world. Going forward, SK Telecom will expand its footprint in the quantum security business by integrating QRNGs to more devices and networks.
