Company profile
Quantum Motion
London company developing quantum computing processors built on standard silicon manufacturing processes rather than bespoke fabrication routes.
Company overview
Quantum Motion develops silicon-based quantum computers, combining silicon-spin qubits with fault-tolerant processor architectures and integrated circuit engineering. Its semiconductor work centres on implementing qubits through conventional CMOS transistor processes, with the aim of using established foundries and manufacturing supply chains. The company reports measuring a single electron spin using a 300 mm CMOS process and characterising 1,024 quantum dots in under five minutes. It delivered a full-stack silicon quantum computing prototype in September 2025 and formalised a partnership with GlobalFoundries in January 2025. Intended applications include chemical, materials and drug discovery, resource optimisation, and artificial intelligence. Founded in 2017 by Simon Benjamin and John Morton, the business opened its central London laboratory and headquarters in February 2022 and also lists an Oxford office. Companies House records Quantum Motion Technologies Limited as active, incorporated on 14 July 2017, with its registered office at 9 Sterling Way, London N7 9HJ.
