en.Wedoany.com Reported - UK-based silicon quantum computing developer Quantum Motion recently announced it has secured $160 million in Series C funding. The round was co-led by DCVC and Kembara, with the British Business Bank and Firgun fund joining as significant new investors. Existing shareholders Oxford Science Enterprises, Inkef, Bosch Ventures, Porsche Automobil Holding, and Parkwalk Advisors fully participated in the follow-on investment. This funding will be used to accelerate the commercialization of scalable quantum systems utilizing existing CMOS manufacturing processes, making the company the most well-funded quantum computing enterprise in the UK.
Quantum Motion's technical approach is based on mature silicon transistor processes, producing qubits by trapping single electron spins in quantum dots, which can be manufactured within standard semiconductor foundries. Compared to approaches requiring purpose-built facilities and megawatts of power supply, this architecture reduces costs and space requirements by two orders of magnitude, with energy consumption dropping to one-thousandth. Last year, the company deployed a full-stack silicon CMOS quantum computer at the UK's National Quantum Computing Centre, demonstrating single-qubit gates, two-qubit gates, entangled state generation, and stable readout within three standard server racks, validating the feasibility of compact deployment.
To secure its supply chain, Quantum Motion is strengthening its manufacturing collaboration with GlobalFoundries, directly importing designs into 300mm wafer production lines. The goal is to embed "utility-scale" quantum processors into data center racks, rather than relying on standalone buildings. Since 2023, the company has added laboratories and offices in Spain and Australia, expanding its team from around 30 people in 2022 to over 120 currently, covering fields such as integrated circuit engineering, quantum theory, and hardware R&D. It is also participating in Phase B of the DARPA Quantum Benchmarking program, driving the system's transition from the lab to industrial environments.
The system operates at temperatures below 1 Kelvin, utilizing commercial cryostats to achieve continuous operation and efficient thermal management. CEO Dr. James Palles-Dimmock described the node where quantum chips reach integration levels equivalent to classical processors as a "transistor moment," stating: "Our goal is to deliver fast, fault-tolerant quantum computing in a single rack, not a building." This enables applications in drug discovery, new materials exploration, and financial services to be deployed directly on existing IT infrastructure. The official announcement regarding this funding and the technical analysis of the silicon-based approach have been publicly released, with Firgun Ventures also simultaneously disclosing investment details.
