Quantum Motion
Quantum Motion is a Silicon-Spin Qubits company founded in 2017 and based in London, United Kingdom.
Quantum Motion was founded in 2017 by John Morton and Simon Benjamin and is headquartered in London, with offices in Oxford, San Sebastián in Spain and Sydney. It builds quantum computers from silicon quantum-dot spin qubits made on 300mm CMOS wafers, the process used for conventional chips, and formalized a manufacturing partnership with GlobalFoundries in January 2025. Its full-stack systems fit standard 19-inch data-center racks, and in 2025 it delivered one to the UK's National Quantum Computing Centre. The company sells complete systems with the hardware and software stack. It raised an £8 million Series A led by INKEF in May 2020 and a £42 million Series B led by Bosch Ventures in February 2023. In May 2026 it raised a $160 million Series C co-led by DCVC and Kembara, with British Business Bank and Firgun as new investors, and in September 2026 it closed a second tranche backed by imec.ventures and Sony Innovation Fund. James Palles-Dimmock is CEO.
Quantum Motion is one of 11 companies DARPA selected in November 2025 for Stage B of its Quantum Benchmarking Initiative, alongside Diraq and Silicon Quantum Computing in the silicon-spin lane. Its approach puts qubits on commercial 300mm lines with GlobalFoundries so production can scale on existing foundry supply chains. The 2025 NQCC system placed a silicon CMOS machine in a national lab, and in April 2026 the company joined a €50 million European pilot line for semiconductor qubit manufacturing.
