Quantum Motion has raised $160 million in Series C funding to accelerate the commercial development of its silicon-based quantum computing technology. The round was co-led by DCVC and Kembara, with participation from the British Business Bank, Firgun, and several existing investors. The financing strengthens Quantum Motion’s position as one of the UK’s most heavily funded quantum computing companies and supports its push toward practical, data-centre-ready quantum systems.
Backing for a Silicon-Based Quantum Strategy
The London-based company is developing quantum computers using silicon transistor technology, the same foundation used in today’s smartphones, laptops, and conventional semiconductor chips. Quantum Motion says this approach could significantly reduce the cost, size, and energy demands associated with building useful quantum computers. Its architecture is designed to fit into standard data-centre racks rather than requiring highly specialised industrial-scale facilities.
Addressing Quantum’s Infrastructure Challenge
The funding arrives as demand for high-performance computing and artificial intelligence infrastructure continues to place growing pressure on energy grids and data-centre capacity. Quantum computing is widely viewed as a major future computing platform, but many competing approaches may require large physical footprints and high power consumption to reach commercial scale. Quantum Motion is positioning its silicon transistor model as a more practical route to utility-scale quantum systems that can be deployed within existing infrastructure.
Commercial Progress and Global Expansion
Since its previous funding round in 2023, Quantum Motion has expanded its international presence with offices and laboratories in Spain and Australia. The company has also strengthened its manufacturing relationship with GlobalFoundries, linking its development roadmap more closely to established semiconductor production processes. In 2025, it deployed a full-stack silicon CMOS quantum computer at the UK’s National Quantum Computing Centre and advanced to Stage B of DARPA’s Quantum Benchmarking Initiative.
Investor Support and Strategic Significance
Quantum Motion’s leadership believes silicon offers one of the strongest pathways to scalable quantum computing because it can draw on decades of progress in chip manufacturing. Investors backing the round view the technology as a potential foundation for future computing, artificial intelligence, and security infrastructure. Returning investors include Oxford Science Enterprises, Inkef, Bosch Ventures, Porsche Automobil Holding SE, and Parkwalk Advisors, underscoring continued confidence in the company’s long-term strategy.
The new capital gives Quantum Motion additional resources to move from technical validation toward broader commercial deployment. By focusing on silicon transistors, established manufacturing supply chains, and compatibility with standard data centres, the company is aiming to reduce some of the biggest barriers facing quantum computing adoption. If its approach scales as planned, Quantum Motion could play a central role in making quantum computers more affordable, energy-efficient, and operationally practical.
