Quantum Motion has raised $160 million in a Series C funding round to support the commercialization of its silicon-based quantum computing technology.

The round was co-led by DCVC and Kembara and saw participation from both existing and new investors – British Business Bank and Firgun.

In a statement, Quantum Motion said the funding will help support the UK-based company’s efforts to deliver “utility-scale and commercially viable quantum computers” that fit inside existing standard data centers and racks.

Quantum Motion was founded in 2017 by Professor John Morton and Professor Simon Benjamin with the aim of developing quantum computers using traditional CMOS chips. Spun out from University College London and Oxford University, where the two professors worked, the company previously raised $50.8 million in 2023.

In April 2025, it was one of 18 companies selected for the first phase of the US’ Defense Advanced Research Projects Agency’s (DARPA) Quantum Benchmarking Initiative (QBI), and in September of that same year, the company delivered a full-stack quantum computer to the National Quantum Computing Centre (NQCC) in Harwell, UK.

“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.”

Co-founders Morton and Benjamin, who are CTO and CSO, respectively, said: “As founders, we were inspired by the breathtaking accomplishments of silicon technology, with city-like complexity delivered on centimeter-scale chips. Now, Quantum Motion’s chips can be used not only for bits but also for qubits, unlocking a future in which quantum computers are both fast and ubiquitous.”
