PsiQuantum Reconnects with UK Roots as Quantum Landscape Evolves

In 2023, PsiQuantum—a Silicon Valley-based quantum computing company founded by four British physicists—opened a major research facility at STFCDealroom has a profile for this one. Try Dealroom →’s Daresbury LaboratoryDealroom has a profile for this one. Try Dealroom → in the UK.

The decision, detailed in a keynote speech at BidwellsDealroom has a profile for this one. Try Dealroom →' Creating a Scientific Superpower event in 2024, was framed as both a strategic and symbolic return to the UK’s academic and technical base in quantum technologies.

Over a year on, PsiQuantum’s presence at Daresbury has taken on added relevance. As the UK government continues to invest in quantum infrastructure through its National Quantum Strategy, the company’s emphasis on cryogenics, photonics, and large-scale engineering fits squarely within national priorities.

PsiQuantum is developing a photonic-based, fault-tolerant quantum computer—an approach requiring high-power cryogenic systems, which Daresbury is uniquely equipped to support.

The UK facility complements PsiQuantum’s primary operations in the US, reflecting a more distributed R&D model and growing international collaboration in quantum science.

In his 2024 keynote, co-founder Mark ThompsonDealroom has a profile for this one. Try Dealroom → noted that returning to the UK was not driven by sentiment, but by a convergence of infrastructure, talent, and policy support conducive to advancing long-horizon technologies.

As of mid-2025, the Daresbury facility continues to serve as a hub for advancing cryogenic subsystems critical to scaling quantum systems. Its development signals a broader shift: the UK is not only supporting quantum startups but also attracting globally backed deeptech companies to embed themselves within its evolving innovation ecosystem. PsiQuantum’s move is both a validation of that trend and a contribution to its momentum.
