PALO ALTO, Calif., March 6, 2023 — PsiQuantum announced today the opening of its UK-based advanced R&D facility at STFC’s Daresbury Laboratory in the north west of England. This effort is backed by £9M (US$10.8M) of funding from the UK government’s Department for Science, Innovation and Technology (DSIT), and gives PsiQuantum access to one of Europe’s largest liquid-helium (approx. -270°C) cryogenic plants.
PsiQuantum has teamed up with STFC’s Daresbury Laboratory to develop the next generation of high-power cryogenic modules which will be necessary to scale photonic quantum computers to millions of qubits. PsiQuantum will work with Daresbury Laboratory experts specialized in large-scale cryogenic infrastructure to develop advanced cryogenic systems.
This partnership will deliver quantum computing subsystems with the highest cryogenic cooling power deployed to date, representing a major step towards large-scale quantum computers capable of solving commercially relevant problems.
PsiQuantum is building an error-corrected quantum computer which harnesses the quantum mechanical properties of single particles of light (photons). Like all leading quantum computing efforts, this requires cryogenic cooling but the advantage of a photonic approach is that the cooling requirements are far less demanding. PsiQuantum’s approach requires cryogenic cooling to operate extremely sensitive single-photon detectors, which are used to read the state of the photonic qubit.
These devices operate at temperatures just a few degrees above absolute zero – equivalent to the temperature of deep space. Although cold, the operating temperature is hundreds of times hotter than the milli-Kelvin temperatures required by many other quantum computing technologies, thus circumventing the unprecedented challenge of developing large-scale milli-Kelvin dilution refrigeration.
Working with STFC’s Daresbury Laboratory will increase PsiQuantum’s cryogenic capabilities 100-fold, with single cryogenic modules capable of delivering 100W of cooling power at liquid-helium temperatures. In addition to supporting larger arrays of quantum chips, this additional cooling power will allow PsiQuantum to implement power-hungry features that are essential for scaling-up quantum computers, including chip-to-chip networking and integrated control electronics.
This collaboration between PsiQuantum, STFC and the UK National Quantum Computing Centre will accelerate PsiQuantum’s roadmap by leveraging the UK’s well-established infrastructure and skill-base, including:
- Collaboration with UK Science and Technology Facilities Council (STFC)
- Access to one of Europe’s largest liquid-helium cryogenic plants
- Access to SciTech Daresbury’s large-scale R&D engineering facilities and workshops
- Cryogenic module development – providing 100W of cooling power
- Access to highly-skilled UK talent and knowledge in cryogenic engineering
- £9M (US$10.8M) of funding from the UK government (DSIT)
Mark Thompson, chief technologist and co-founder at PsiQuantum, said: “We are very excited to be setting up a lab in the UK in collaboration with the STFC’s Daresbury Laboratory. The UK has a long history in quantum technologies and a talent pool of exceptional quantum engineers. The STFC team and facilities are world class, with a deep history of accomplishments in large-scale scientific infrastructure. Access to existing cryogenic infrastructure and expertise accelerates PsiQuantum’s mission to deliver a large-scale quantum computer.”
Powered by breakthroughs in silicon photonics and fault-tolerant quantum architecture, PsiQuantum is building the first utility-scale quantum computer to solve some of the world’s most important challenges. PsiQuantum’s approach is based on single-photon qubits, which have significant advantages at the scale required to deliver a fault-tolerant, general-purpose quantum computer. With their photonic chips manufactured in a world-leading semiconductor fab, PsiQuantum is uniquely positioned to deliver quantum capabilities reaching the scale needed to drive advances in climate technologies, pharmaceuticals, healthcare, finance, energy, agriculture, transportation, communications, and beyond.
