About
Quantum Motion is a London-based quantum computing company building silicon CMOS transistor-based quantum computers for standard data centers 12. The company’s silicon-based approach targets a 100-fold reduction in cost and space requirements and a 1,000-fold reduction in energy consumption compared to alternative quantum architectures 1. In September 2025, Quantum Motion unveiled what it described as the world’s first full-stack quantum computer on standard silicon chips, now deployed at the UK’s National Quantum Computing Centre 1. The company was selected by DARPA for Stage B of the Quantum Benchmarking Initiative in late 2025 1. The $160M Series C announced May 7, 2026 will fund commercialization of utility-scale silicon quantum systems 12.

What Investors Say
Dr. Prineha Narang, DCVC Operating Partner, stated: “Quantum is critical infrastructure for the next century of computing, AI, and security, and leadership will go to whoever can industrialise it.” 1
Yann de Vries, Kembara Partner, said: “Which of the many ways of building one will actually work at scale? This investment signals our strong belief in where the answer lies.” 1
What Founders Say
Dr. James Palles-Dimmock, CEO, said: “Quantum computing will only achieve its full potential if it can be built on a platform that scales, and we believe silicon is the strongest route.” 1
