Quantum Motion Raises £160M Series C, UK's Best-Funded Quantum Firm

London-based Quantum Motion, a developer of silicon-based quantum computers, announced a 160 million pound Series C funding round on Thursday, positioning it as the United Kingdom's best-funded quantum computing company with more than 200 million pounds raised to date.

The round was co-led by U.S. venture capital firm DCVC and Spanish deeptech investor Kembara. New participants included the British Business Bank and Firgun, while existing backers such as Oxford Science Enterprises, Inkef, Bosch Ventures, Porsche Automobil Holding SE and Parkwalk Advisors also joined.

Quantum Motion uses silicon transistor technology, the same employed in smartphones and laptops, to build fullstack quantum computers. These systems incorporate a quantum processing unit, user interface and control stack compatible with standard quantum software. The company claims its approach delivers a 100-fold reduction in cost and space requirements, along with a 1,000-fold decrease in energy consumption compared to alternative architectures.

The funding will support commercialization efforts, further research and development, and international expansion. Founded in 2017 by Professor John Morton of University...
