Silicon-Based Approach Offers Cost and Energy Benefits
Quantum Motion, renowned for its silicon transistor-based quantum computing approach, recently achieved a significant milestone. The company successfully raised $160 million in a Series C funding round, announced on 7th May 2026, to advance its scalable and energy-efficient quantum computing technology.
DCVC and Kembara co-led the funding round, with participation from the British Business Bank and Firgun. This positions the company as the UK’s leading quantum computing firm in terms of funding, aiming to deliver utility-scale systems that seamlessly integrate into existing data centres.
Utilising silicon transistor technology, Quantum Motion’s solutions promise a dramatic 100-fold reduction in both cost and space requirements. They offer a 1,000-fold reduction in energy consumption compared to other existing quantum computing methods. These systems utilise the same silicon technology found in everyday devices such as smartphones and laptops.
Industry and Global Expansion
Quantum Motion has been expanding its global footprint since its last funding round in 2023. The company opened new offices and labs in Spain and Australia, further strengthening its international presence. It has deepened its manufacturing collaboration with GlobalFoundries, ensuring its roadmap aligns with commercial semiconductor supply chains.
Dr. James Palles-Dimmock, CEO of Quantum Motion, emphasised, “Quantum computing will only achieve its full potential if it can be built on a platform that scales, and we believe silicon is the strongest route to achieving that.”
In a pioneering move, 2025 saw Quantum Motion deploy the world’s first commercial full-stack silicon CMOS quantum computer at the UK National Quantum Computing Centre. This focus on industrial scalability sets them apart within the quantum computing industry.
Returning investors in this funding round include notable names such as Oxford Science Enterprises, Inkef, Bosch Ventures, Porsche Automobil Holding SE, and Parkwalk Advisors. Their continued support underscores confidence in Quantum Motion’s innovative approach.
The current funding surge occurs at a crucial time for the computing industry. Governments and businesses are heavily investing in next-generation high-performance computing (HPC) and AI systems, which demand substantial capital and infrastructure. Quantum Motion’s technology offers a viable alternative, reducing the strain on power grids tested by AI data centres.
Unlike other quantum computing ventures that often focus on qubit counts and laboratory experiments, Quantum Motion prioritises industrial scalability. By advancing to Stage B of DARPA’s Quantum Benchmarking Initiative, the company continues to solidify its leadership and commitment to practical, scalable quantum solutions.
The financing round comes at a defining moment for the computing industry. As governments and industry invest heavily in next-generation HPC and AI systems, vast capital and infrastructure investments are demanded. Quantum is set to become the next wave of computing, straining a power grid already tested by AI data centres. In other approaches, a useful quantum computer is expected to demand infrastructure on an industrial scale, including multi-megawatt power consumption. Quantum Motion’s silicon transistor-based architecture enables delivering utility-scale systems with significant reductions in cost, space, and energy consumption compared to alternatives.
