UK-headquartered Quantum Motion has closed a $160m (£117.5m) Series C round to commercialise its scalable and energy-efficient approach to quantum computing.
Quantum Motion builds utility-scale quantum computers using industry-standard silicon transistors. Built on qubits using the silicon technology found in smartphones and computers, its systems are designed for deployment into standard data-centre racks. This avoids the need for bespoke facilities and the heavy energy overheads associated with alternative architectures.
Alongside new investors DCVC, Kembara, British Business Bank and Firgun, the Series C round is joined by returning backers Oxford Science Enterprises, Inkef, Bosch Ventures, Porsche Automobil Holding SE and Parkwalk Advisors.
Since its last funding round in 2023, the company has expanded internationally and opened new offices and labs in Spain and Australia.
“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,” says 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.”
The significant financing round comes at a defining moment for the computing industry, as governments and industry invest heavily in quantum.
In March, a new programme worth up to £2bn of UK government investment was launched to ‘keep the UK at the forefront of quantum innovation’.
