Quantum Motion: $160 Million Series C Raised For Silicon-Based Quantum Computing Platform

By Amit Chowdhry • Today at 7:28 AM

Quantum Motion announced it raised $160 million in a Series C financing round to accelerate the commercialization of its silicon transistor-based quantum computing technology. The financing was co-led by DCVC and Kembara, with participation from the British Business Bank, Firgun, and existing investors.

The company said the funding will support the development of utility-scale quantum computers designed to operate within existing data center infrastructure using standard semiconductor manufacturing approaches.

Quantum Motion develops quantum computing systems based on silicon transistor technology similar to the semiconductor architectures used in smartphones and traditional computing chips. The company said its approach is designed to reduce cost, space requirements, and energy consumption compared to alternative quantum computing architectures.

According to Quantum Motion, its systems are designed to achieve approximately 100-fold reductions in cost and space requirements and 1,000-fold reductions in energy consumption relative to competing approaches. The company said its quantum computers are intended to fit into standard data center racks without requiring specialized facilities or industrial-scale power infrastructure.

Since its previous financing round in 2023, Quantum Motion has expanded its operations internationally, opening new offices and laboratories in Spain and Australia, and has strengthened its manufacturing partnership with GlobalFoundries.

The company also announced it completed what it described as the world’s first commercial deployment of a full-stack silicon CMOS quantum computer at the UK National Quantum Computing Centre in 2025 and advanced to Stage B of DARPA’s Quantum Benchmarking Initiative.

Quantum Motion said its long-term strategy focuses on industrial scalability rather than headline qubit counts or laboratory demonstrations. The company operates offices and laboratories in the United Kingdom, Spain, and Australia.

KEY QUOTES:

“Today’s announcement reflects the strength of the team we have built and the progress they have delivered. 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. We are pleased to be joined by investors who share our vision and understand what it takes to build a foundational company in this field.”

Dr. James Palles-Dimmock, CEO, Quantum Motion

“As founders we were inspired by the breathtaking accomplishments of silicon technology, with city-like complexity delivered on centimetre scale chips. Now, Quantum Motion’s chips can be used not only for bits but also for qubits, unlocking a future in which quantum computers are both fast and ubiquitous.”

Dr. John Morton, CTO, And Dr. Simon Benjamin, CSO, Quantum Motion

“Quantum is critical infrastructure for the next century of computing, AI, and security, and leadership will go to whoever can industrialise it. DCVC led this investment in Quantum Motion because silicon is the foundation that scales, and this team is building on the CMOS advantage to turn quantum from a demonstration into a commercial success story.”

Dr. Prineha Narang, Operating Partner, DCVC

“If you believe quantum computing is going to be world-changing, as we do, then the obvious next question is which of the many ways of building one will actually work at scale? This investment signals our strong belief in where the answer lies.”

Yann de Vries, Partner And Co-Founder, Kembara

“The race for a fully scalable quantum computer is one of the defining technological challenges of our time. Quantum Motion’s unique approach that combines cutting-edge quantum physics with established silicon manufacturing provides a distinct global edge. We are no longer just theorizing about quantum computing but are actively starting to build the platforms to deliver it here in the UK.”
