Infleqtion

Infleqtion is a US quantum computing and quantum sensing company headquartered in Boulder, Colorado, and one of the firms named in the UK governments PS2bn quantum deployment strategy. The company focuses on cold-atom-based quantum systems, which use laser-cooled atoms as qubits, and has developed products spanning quantum computing hardware, atomic clocks, and navigation sensors. Its inclusion in the UK strategy reflects the governments intent to source quantum hardware internationally rather than limiting procurement to British-only suppliers.

Founded in 2007 (as ColdQuanta) and rebranded as Infleqtion in 2022, the company has received backing from the US Department of Defense and NASA alongside private investors. It has partnerships with IBM and has won contracts under the US National Quantum Initiative. Infleqtion rebranded to signal a broader commercial ambition beyond its academic origins.

For the UK quantum ecosystem, Infleqtions presence as a named partner in the national deployment plan is significant because it indicates the government is willing to work with US-headquartered quantum hardware suppliers rather than waiting for domestic alternatives to mature. This approach accelerates deployment timelines but raises questions about supply chain sovereignty that the MOD and NCSC are expected to address through security annexes in any procurement contracts.
