Founded by four UK professors in 2016, PsiQuantum set out with the ambitious goal of building the world's first large-scale, fault-tolerant, error-corrected quantum computer. After securing substantial funding and support in the US, the company grew to 300 employees and achieved a valuation of over $3 billion. Thompson highlights the unique advantages of Silicon Valley, including access to talent, a thriving ecosystem, and a culture that fosters rapid growth.

However, PsiQuantum's recent expansion back to the UK showcases the country's strength in cryogenic expertise and its potential as a science superpower. By establishing an R&D facility at Daresbury Laboratories, PsiQuantum has leveraged the UK's specialized infrastructure and supply chain to accelerate their development roadmap. Thompson emphasises the significance of the UK's research innovation and the need to strengthen the special relationship with the US to maximise benefits for both nations.
