About Quantum Motion
Quantum Motion
On September 15, 2025, Quantum Motion delivered the first full-stack silicon CMOS quantum computer at the UK National Quantum Computing Centre, built on a 300-mm wafer process that integrates a quantum processing unit, cryogenic control electronics and a dilution refrigerator into a footprint of just three 19-inch racks. The system combines Quantum Motion’s Quantum Processing Unit with a user interface and control stack compatible with Qiskit and Cirq, offering a complete data-centre-friendly solution that can be upgraded to larger processors without altering its physical envelope. This milestone demonstrates that a robust, functional quantum computer can be mass-produced using the same transistor technology underpinning conventional silicon chips. In October 2025, Isobel C. Clarke, Virginia Ciriano-Tejel, David J. Ibberson, and colleagues at Quantum Motion achieved single-shot spin readout directly within a standard 22 nanometer integrated circuit, converting spin information into a measurable electrical signal with exceptional visibility exceeding 90% and observing millisecond spin relaxation times.
