Summary

Quantum Motion, a UK-based quantum computing company, has secured a $160 million Series C funding round. This investment is among the largest for a European quantum computing startup, following IQM's $320 million Series B and Pasqal's $200 million equity round. The Series C was co-led by DCVC and Mundi Ventures, with participation from British Business Bank, Firgun Ventures, Oxford Science Enterprises, Inkef, Bosch Ventures, and Porsche. Quantum Motion, which spun out of Oxford University, develops "dot spin qubits" using silicon, aiming for integration with existing semiconductor production infrastructure. The company recently opened new offices in San Sebastian, Spain, partnering with CIC Nanogune, and plans to hire 50 employees there, adding to its current team of 100. It has already delivered a quantum computer to the UK National Quantum Computing Centre.

Key takeaway

For investors evaluating deeptech opportunities, Quantum Motion's $160 million Series C highlights significant capital flow into quantum computing, particularly for approaches leveraging existing semiconductor infrastructure. Your due diligence should prioritize companies demonstrating clear paths to scalability and commercialization, such as Quantum Motion's partnership with Global Foundries and delivery to the UK National Quantum Computing Centre, as the sector rapidly matures.
