UK Quantum Motion Startup Raises $160M Funding In Series C Round

The round was co-led by DCVC and Kembara, with participation from British Business Bank, Firgun, and existing investors.
Quantum Motion is developing quantum computers based on silicon transistor technology the same foundation used in modern smartphone and laptop chips.

The company says this approach can reduce cost and space requirements by 100x and lower energy consumption by 1,000x compared to alternative quantum computing architectures.

Its systems are designed to fit inside standard data centre racks, eliminating the need for large custom-built facilities and reducing the infrastructure burden associated with quantum computing.

Since its previous funding round in 2023 Quantum Motion has expanded operations into Spain and Australia and strengthened its manufacturing partnership with GlobalFoundries.

The company also achieved the first commercial deployment of a full-stack silicon CMOS quantum computer at the UK National Quantum Computing Centre in 2025 and advanced to Stage B of DARPA’s Quantum Benchmarking Initiative, highlighting its focus on industrial scalability rather than experimental demonstrations alone.

“Today’s announcement reflects the strength of the team we have built and the progress they have delivered. 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 to achieving that,” said Dr. James Palles-Dimmock, CEO of Quantum Motion. “We are pleased to be joined by investors who share our vision and understand what it takes to build a foundational company in this field.”

About Quantum Motion

Quantum Motion founded in 2017 develops scalable quantum computing technology using silicon based qubits and CMOS-compatible manufacturing processes. The company aims to build energy-efficient utility-scale quantum computers that integrate with existing semiconductor infrastructure and standard data centres, making quantum computing more practical, scalable and commercially accessible.
