The company now has access to one of Europe's largest liquid-helium (approximately -270°C) cryogenic reactors, thanks to $10.6 million (£9 million) in financing from the UK government's new Department for Science, Innovation and Technology (DSIT).
PsiQuantum has partnered with STFC's Daresbury Laboratory to create the next generation of high-power cryogenic modules required to grow its photonic quantum computers to millions of qubits. PsiQuantum researchers will collaborate with Daresbury’s large-scale cryogenic infrastructure specialists to build improved cryogenic systems.
The partnership will produce quantum computing subsystems with the most cryogenic cooling power yet deployed, marking a significant step toward large-scale quantum computers capable of tackling commercially-applicable issues.

These devices operate a few degrees above absolute zero or deep space temperature. While the working temperature is frigid, it is hundreds of times higher than the milli-Kelvin temperatures needed by many other quantum computing methods, avoiding the enormous problem of establishing large-scale milli-Kelvin dilution refrigeration.
PsiQuantum aims to increase its cryogenic capabilities a hundredfold through the STFC collaboration, resulting in a single cryogenic module capable of supplying 100W of cooling power at liquid-helium temperatures. This added cooling power will enable PsiQuantum to include the many energy-intensive features needed to scale quantum computers, such as chip-to-chip networking and integrated control circuits. It will also support a more comprehensive array of quantum chips.
"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," said PsiQuantum chief technologist and co-founder Mark Thompson.
