About
Quantum Motion is a UK quantum computing company founded in 2017 out of Oxford and UCL, based in London. In September 2025 it delivered the UK's first full-stack silicon CMOS quantum computer to the National Quantum Computing Centre (NQCC). The system is built on a 300mm wafer using standard CMOS fabrication, with a 1,024 quantum dot array validated in under 5 minutes, 100 times faster than previous validation. Its systems are compatible with Qiskit and Cirq. In May 2026 the company raised a $160M Series C co-led by DCVC and Kembara, taking total funding past $200M, and it manufactures with GlobalFoundries. It also partners with ORCA Computing and Riverlane on the QUICHE project. Goldman Sachs partnered with Quantum Motion on options pricing quantum algorithms, establishing the company in quantum finance applications. Quantum Motion demonstrated the world's fastest dispersive readout of a silicon spin qubit, with state determination of about 8 µs using RF electron cascade, published in Nature Electronics. It also integrated a 384-qubit silicon quantum dot chip that combines quantum devices with cryogenic CMOS control electronics. In February 2026 the company opened a European subsidiary in San Sebastián, Spain, deepening its engagement with the Basque quantum ecosystem.
