Quantum Motion raises $160m Series C as quantum sector heats up

Quantum Motion, the UK-based company building quantum computers, has raised a $160m Series C.
The round is one of the largest fundraises secured by a European quantum computing startup, after Finland’s IQM, which closed a $320m Series B last year, and French scaleup Pasqal, which recently completed a $200m equity funding round.
The Series C was co-led by US multi-stage investor DCVC and Spain-based growth firm Mundi Ventures through its deeptech fund Kembara. It included participation from the British Business Bank and UK-based VC Firgun Ventures.
Historical investors Oxford Science Enterprises, Inkef, and German multinationals Bosch Ventures and Porsche also joined the round.

It comes three months after Quantum Motion announced the opening of new offices in San Sebastian in Spain, where the scaleup is partnering with Spanish research centre CIC Nanogune to develop quantum computers. Quantum Motion also has offices in London, Oxford and Sydney.
The scaleup plans to hire a team of 50 employees in Spain, in addition to its current team of 100.
Quantum computers, which leverage the laws of quantum physics, are expected to unlock vast amounts of computing power once they reach a certain scale, with significant impacts in fields ranging from AI to finance and pharmaceuticals.
Startups and Big Tech companies are racing to build a fully-fledged device. To do so, they are exploring different ways of creating qubits, the quantum particles that sit inside the computers’ processors and are key to carrying out quantum calculations.
Quantum Motion, which originally spun out of Oxford University, is building “dot spin qubits”, meaning quantum information is stored in the spin of a single electron, which is then trapped in silicon.
Because silicon is a standard material used to fabricate classical semiconductors, the company says its technology can be integrated into existing production infrastructure and scaled at pace. Quantum Motion is working in partnership with US chipmaker Global Foundries to develop its devices.
Quantum Motion has already delivered one quantum computer to the UK National Quantum Computing Centre (NQCC), which the company says was manufactured using standard semiconductor fabrication processes.
The Series C funding will help the scaleup commercialise more devices.
The move comes as the sector heats up fast, with European startups in the sector securing €1.6bn in 2025, according to Sifted data, more than doubling the €700m raised in 2024.
Quantum Motion’s Series C is the third megaround in the sector in Europe this year, following Pasqal’s $200m fundraise and a $178m Series B bagged by Dutch quantum startup Quanttware earlier this week.
