Quantum Motion, the UK‑based quantum‑computer startup, closed a €160m Series C led by DCVC and Mundi Ventures' Kembara fund. The round also drew the British Business Bank, Firgun Ventures, Oxford Science Enterprises, Inkef, Bosch Ventures and Porsche. Three months after opening a San Sebastián office, the company plans to deliver quantum processors dot‑spin qubits and Foundries manufacturing.

The funding comes as European quantum startups have raised €1.6bn in 2025, more than double last year’s €700m. Quantum Motion’s deal ranks third largest in the region after IQM’s $320m Series B and Pasqal’s $200m round. The capital will help the firm commercialise silicon‑based qubits and expand its San Sebastián research partnership to production timelines the UK National Quantum Computing Centre’s demand.

Quantum Motion, spun out of Oxford University, stores quantum data in the spin of single electrons trapped in silicon, allowing integration with existing semiconductor fabs. The firm shipped a processor to the UK National Quantum Computing Centre and now seeks to scale output with the new cash. Investors expect the round to push the company closer to mass‑produced quantum machines.
