Firgun Ventures, a $250 million quantum technology fund, has made its first European investment. The firm is participating in a $160 million Series C funding round for Quantum Motion, a London-based quantum computing company. Co-leads include DCVC and Kembara. Other participants are the British Business Bank, Oxford Science Enterprises, Inkef, Bosch Ventures, Porsche Automobil Holding SE, and Parkwalk Advisors.
Quantum Motion develops full-stack quantum computers using standard 300 mm silicon CMOS fabrication processes—the same technology used in conventional semiconductors. The architecture is designed to scale to millions of qubits, enabling fault-tolerant and commercially viable quantum computing.
The investment marks Firgun’s entry into the European market. Previous Firgun investments include Photonic Inc. (distributed quantum computing and communications) and Quantum Elements (an AI platform for quantum applications).
Quantum Motion was founded in 2017 by Professor John Morton (UCL) and Professor Simon Benjamin (University of Oxford). The company employs more than 100 people across the UK, the US, Australia, and Spain. In September 2025, Quantum Motion demonstrated the world’s first full-stack quantum computer built on standard silicon chips. That system is now deployed at the UK National Quantum Computing Center (NQCC) for research applications, including drug discovery.
Additionally, Quantum Motion was selected to advance to Stage B of the US Defense Advanced Research Projects Agency (DARPA) Quantum Benchmarking Initiative (QBI) in late 2025.
Prior to this Series C, the company raised over £62 million in equity and grant funding. That included an oversubscribed £42 million Series B led by Bosch Ventures and Porsche SE, which supported the expansion and development of silicon quantum processors.
