Quantum Motion develops quantum computers using silicon and CMOS semiconductor manufacturing. Its website says it is building utility-scale quantum computers using a silicon-spin architecture designed to work with standard silicon processing and existing foundry supply chains. The company also states that it combines fault-tolerant quantum architecture expertise with hardware knowledge to realize qubits in silicon.
The company says its approach is aimed at manufacturable, scalable quantum processors suitable for data-centre deployment. Its About page states that Quantum Motion was founded in 2017 by Simon Benjamin and John Morton, and that it opened its lab and headquarters in central London in February 2022. The site also lists a Series A of £8 million in May 2020, a Series B of £42 million in February 2023, and a Series C of $160 million in May 2026.
