DCVC and Kembara co-led the financing, joined by the British Business Bank, Firgun and existing investors, to speed commercialisation of silicon quantum computers.
The company says its transistor-based systems can fit standard data-centre racks and cut cost and space needs by about 100 times and energy use by 1,000 times.
Since 2023, Quantum Motion has expanded into Spain and Australia, deepened ties with GlobalFoundries, deployed a full-stack silicon CMOS quantum computer in the UK and reached DARPA benchmarking Stage B.
With a $10 million price tag, what specific quantum advantage will businesses actually gain from these new machines?
Can the UK's massive quantum investment create a global leader despite US export controls and fierce international competition?
How will Quantum Motion solve the critical power and material shortages that threaten its silicon-based quantum computers?
In May 2026, UK-based Quantum Motion secured a record $160 million Series C funding, driven by its innovative use of silicon CMOS technology for quantum processors. This approach offers scalability, cost-effectiveness, and energy efficiency, enabling quantum computers that fit within standard data centers. The funding aligns with the UK government's £2 billion quantum technology programme and supports Quantum Motion's roadmap toward fault-tolerant quantum computing, building on milestones like the 2025 installation of their full-stack quantum computer and the Bloomsbury chip developed with GlobalFoundries. Meanwhile, growing computational demands and energy challenges in classical computing are accelerating market growth for quantum technologies, which are poised to impact fields such as healthcare, clean energy, and AI.
