Infleqtion UK

The UK arm of Infleqtion, with a base at Oxford Technology Park, working on neutral-atom quantum computers, atomic clocks and quantum sensors.

About Infleqtion UK

Infleqtion works with neutral atoms, atoms cooled with lasers and held in place so they can be used as qubits or as extremely precise sensors. In the UK its work covers three main areas. One is quantum computing: in July 2024 it installed the first neutral-atom quantum computer at the National Quantum Computing Centre (NQCC) at Harwell, and later coverage describes a 100-physical-qubit machine delivered there. The second is timing: Tiqker, which the company calls the first commercially available optical atomic clock, was delivered to the University of Strathclyde in June 2024. The third is sensing, including quantum radio-frequency sensing and quantum navigation that works without GPS.

Infleqtion is a US-headquartered group which the sources describe as having more than 17 years of experience commercialising neutral-atom quantum technology, and it has had a UK presence for several years. Leaders have described the aim as building 'sovereign UK quantum capability' and, in a 2024 statement from its UK president Tim Ballance, as 'leading the UK's quantum revolution' so that the UK 'leads on the global stage'. More recent coverage names Colin Sullivan as managing director of Infleqtion UK, so leadership has probably changed over time.

The UK base is in Oxford. In 2024 the company moved to a 7,500 square foot facility at Oxford Technology Park to support growth and research and development. In 2026 it announced a new Quantum Innovation Centre at the same park, which it says will triple its UK capability and act as a hub for research, manufacturing and systems integration, with manufacturing in Oxford and Harwell. The company has also worked with Nu Quantum of Cambridge on a neutral-atom networking project, and licensed a fibre optics package to the UK firm Thorlabs under the QT Assemble project.

The 2026 announcement says the new centre aims to attract physicists, engineers, software developers and systems integration specialists, and describes a domestic skills base that has already been built. We did not find staff numbers for the UK team. Because the pages we read are announcements, we have no first-hand account of culture.

The UK work is unusual in mixing computers, clocks and sensors that could one day help aircraft, ships and mobile networks navigate and communicate. Physics, engineering and computing graduates are typical hires. Infleqtion's website lists current UK roles.
