Quantum Motion, a UK quantum computing company founded by researchers from Oxford University and University College London, has raised $160 million in a Series C funding round co-led by DCVC and Kembara.
Other investors include Firgun and returning backers such as Oxford Science Enterprises, Inkef, Bosch Ventures, Porsche Automobil Holding SE, and Parkwalk.
A key part of this funding round is a £40 million anchor investment from the British Business Bank, which is its largest single investment in a quantum computing company. The Bank had previously invested £5 million in Quantum Motion’s 2023 Series B.
Quantum Motion was founded in 2017 by Dr John Morton and Dr Simon Benjamin, physicists from Oxford and UCL. The company is working on quantum computers that use standard silicon chips, which are also found in smartphones and laptops.
Using silicon, which is already manufactured at scale by the global semiconductor industry, is the best way to build quantum computers that can scale to millions of qubits for commercial use. The global quantum computing market was valued at approximately $1.5 billion in 2025 and is projected to reach $18 billion by 2034, with a compound annual growth rate exceeding 31%.
Quantum Motion and its Australian competitor, Diraq, are leading companies developing silicon-spin qubits. This technology places quantum bits directly onto silicon chips using methods compatible with current semiconductor factories.
If qubits can be made like transistors, the quantum industry can leverage the existing global chip manufacturing system rather than building new factories. Quantum Motion has already shown that this approach works.
Before this funding round, Quantum Motion became the first to deploy a full-stack quantum computer built on standard silicon chips at the UK National Quantum Computing Centre. This system includes hardware, software, and control electronics, all running on the same material as consumer chips.
“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 theorising about quantum computing but are actively starting to build the platforms to deliver it here in the UK,” says Charlotte Lawrence, managing director of direct equity, British Business Bank.
The fresh round will speed up the development of scalable, commercially ready quantum computers and support the company’s ongoing global research expansion.
