Infleqtion opens Oxford quantum hub after delivering 100-qubit system

Infleqtion is tripling its UK quantum footprint with a new Oxford centre, betting on sovereign manufacturing after delivering the country's first 100-qubit computer.

Infleqtion is tripling its UK research and production capacity with a new Oxford Quantum Innovation Centre, doubling down on sovereign quantum manufacturing after delivering Britain's first 100-physical-qubit computer.

"The UK has become a global quantum leader through sustained government support, academic excellence, and industrial investment," Colin Sullivan, Managing Director of Infleqtion UK, said. "After more than a decade in the UK quantum ecosystem, we've built a sovereign skills base and invested heavily in onshore technology."

The facility at Oxford Technology Park will triple Infleqtion's research, production and systems integration footprint. The company delivered the UK's first operational 100-physical-qubit system to the National Quantum Computing Centre at Harwell, meeting the government's 2025 target — a milestone the Department for Science, Innovation and Technology cited when it announced as much as £2 billion in long-term quantum investment.

The expansion aligns with the UK's ProQure procurement programme, which aims to acquire large-scale quantum systems beyond 2030. Infleqtion also leads a £2.2 million programme with the NQCC and Quantum Software Lab targeting 10-to-100-times improvements in gate speed and parallel processing, putting the company in line to capture a share of the UK's growing quantum budget.

Infleqtion's UK push comes as the government scales investment through its National Quantum Strategy and the Quantum Leap initiative. The company has already demonstrated operational deployments: its Tiqker optical atomic clock completed sea trials aboard the Royal Navy's Excalibur autonomous submarine in October 2025, the first quantum optical clock to operate on an underwater vessel. Royal Navy trials are set to resume in late June.

On the defence side, Infleqtion is advancing Quantum Direction Finding, an Innovate UK-funded programme using Rydberg-atom broadband sensing. It is the only company with contracted atom-based RF sensing programmes across all three AUKUS partners, working with prime integrators including Dell Federal, L3Harris and SAIC.

Infleqtion's neutral-atom platform competes with superconducting approaches from Rigetti Computing and ion-trap systems from IonQ. Unlike Rigetti, which operates a dedicated quantum foundry in California using atomic layer etch tools from Oxford Instruments, Infleqtion is building its manufacturing base in the UK. The company's full-stack approach combines hardware with its Superstaq software platform, already deployed by the US Department of War, NASA and NVIDIA. Infleqtion and NVIDIA published the world's first demonstration of a materials science application using logical qubits.

Infleqtion trades on the NYSE under INFQ after merging with Churchill Capital Corp X. The company's UK bet reflects a broader industry shift toward onshore quantum production, as governments prioritise sovereign capability over imported technology. With the UK committing £2 billion to quantum and Infleqtion already meeting key national milestones, the company is positioned to capture a significant share of that spending — though the path to fault-tolerant, utility-scale quantum computing remains years away.
