Quantum Motion, a developer of silicon transistor-based quantum computers, has closed a $160 million Series C funding round. The investment was co-led by DCVC and Kembara (the deep-tech fund of Mundi Ventures), with significant new participation from the British Business Bank and Firgun. The round also saw full support from existing investors, including Oxford Science Enterprises, Inkef, Bosch Ventures, Porsche Automobil Holding SE, and Parkwalk Advisors. This financing positions Quantum Motion as the UK’s best-funded quantum computing company and is intended to accelerate the commercialization of utility-scale systems that utilize existing CMOS manufacturing processes. The Silicon Transistor Advantage Quantum Motion’s architecture is built on the premise that quantum information can be processed using the same silicon transistor technology found in modern smartphones and laptops. By utilizing quantum dots to trap single electron spins, the company can manufacture qubits within standard semiconductor foundries. This approach offers a significant reduction in physical and resource overhead compared to other modalities; the company reports a 100-fold reduction in cost and space requirements and a 1,000-fold reduction in energy consumption relative to industrial-scale architectures that require bespoke, multi-megawatt facilities. Deployment and Manufacturing Integration The Series C follows the 2025 deployment of a full-stack silicon CMOS quantum computer at the UK National Quantum Computing Centre (NQCC). This system demonstrated single and two-qubit gates, entanglement, and reliable measurement within a footprint of only three standard server racks. To ensure a scalable supply chain, Quantum Motion has deepened its manufacturing partnership with GlobalFoundries, allowing its roadmap to integrate directly into commercial 300mm wafer production lines. This strategy aims to deliver “utility-scale” processors that fit within existing data center racks rather than requiring dedicated buildings. International Expansion and Talent Growth Since 2023, Quantum Motion has expanded its global operations, opening new laboratories and offices in Spain and Australia to
