London based quantum computing company Quantum Motion has secured $160 million in Series C funding as it advances its mission to build scalable full stack quantum computers using silicon chip technology. The investment marks one of the largest funding rounds for a UK quantum startup and strengthens the company’s position within the rapidly growing global quantum computing race.
Major Investors Back Silicon Quantum Technology
The funding round was co led by DCVC and Kembara, with participation from British Business Bank and Firgun.
Existing investors also joined the round, including Oxford Science Enterprises, Inkef, and Bosch Ventures.
With this latest raise, Quantum Motion says it has now secured more than $200 million in total funding, making it the best funded quantum computing company in the UK.
Bringing Quantum Computing to Silicon Chips
Quantum Motion is pursuing a different path from many other quantum computing companies by building its systems using silicon based technology similar to the chips found in laptops and smartphones.
The company believes this approach could enable quantum computers to be produced more affordably, more efficiently, and at greater scale than rival technologies.
According to Quantum Motion, leveraging silicon manufacturing methods could reduce costs and space requirements by up to 100 times while lowering energy consumption by as much as 1,000 times compared with alternative quantum architectures.
Building a Full Stack Quantum System
Unlike companies focused solely on quantum processors, Quantum Motion is developing full stack quantum computers. This means the company is building every layer required to operate a complete quantum system.
Its platform includes the quantum processing unit, user interfaces, and the control stack needed to run standard quantum computing software.
By developing integrated systems rather than isolated hardware components, Quantum Motion aims to accelerate the commercial deployment of practical quantum computing infrastructure.
Academic Foundations and Deep Research Expertise
Quantum Motion was founded in 2017 by John Morton, a professor at the London Centre for Nanotechnology at University College London, and Simon Benjamin of University of Oxford.
The company emerged from years of academic research into silicon based quantum systems and has since expanded into an international operation.
Today, Quantum Motion operates from headquarters in London while also maintaining offices and laboratories in Spain, Australia, and the United States.
Scaling Commercialisation and Research
The newly raised funding will support further research and development while helping the company commercialise its technology.
Quantum Motion also plans to expand geographically as demand for quantum computing infrastructure continues to grow globally.
According to CEO James Palles-Dimmock, the company believes quantum computing will only reach its full potential if it can be built on a platform capable of scaling efficiently.
The company sees silicon as the most promising route to achieving this goal because it can leverage decades of semiconductor manufacturing advancements already established across the global electronics industry.
The Global Race for Quantum Leadership
Quantum computing is increasingly viewed as one of the most strategically important technologies of the coming decades. Governments, technology companies, and investors are pouring billions into the sector in pursuit of systems capable of solving problems beyond the reach of classical computers.
Potential applications include advanced materials research, drug discovery, optimisation, cryptography, and complex simulations.
Quantum Motion’s focus on silicon based systems positions it within a growing movement aimed at making quantum hardware more manufacturable and commercially viable.
Strengthening Europe’s Quantum Ecosystem
The funding also highlights growing momentum within Europe’s deeptech ecosystem as the region seeks to strengthen its position in quantum technologies.
With significant new capital, international expansion plans, and a scalable silicon based approach, Quantum Motion is aiming to become a key player in the next era of computing infrastructure.
