Quantum Motion Raises $160M Series C

Quantum Motion, a leading company in silicon transistor-based quantum computing, announced a $160 million Series C funding round. The round was co-led by DCVC and Kambara, with new investors including the United Kingdom — British Business Bank and Firgun, alongside existing backers like Oxford Science Enterprises, INKef Capital, VSR Ventures Private Limited, Porsche SE, and Parkwalk Advisors. This financing will enable Quantum Motion to commercialize its scalable and energy-efficient quantum computers, designed to fit into standard data centers. The company's approach uses silicon technology, similar to that found in smartphones, offering significant reductions in cost, space, and energy consumption compared to alternative quantum architectures. Since its last funding round in 2023, Quantum Motion has expanded internationally, opening offices and labs in Spain and Australia, and strengthened its manufacturing partnership with GlobalFoundries. The company also deployed the world's first commercial full-stack silicon CMOS quantum computer at the UK National Quantum Computing Centre in 2025 and is advancing in United States — DARPA's Quantum Benchmarking Initiative. CEO James Palles-Dimmock and co-founders John Morton and Simon Benjamin expressed confidence in silicon as the future of scalable quantum computing.
