EU's Scaleup Europe Fund Places First Major Bet on UK Quantum Startup with $160M Investment

London quantum startup Quantum Motion secures $160 million from the European Union's newly launched Scaleup Europe Fund—the bloc's first major late-stage commitment to a post-Brexit UK company.

The investment, led by the EU's flagship venture initiative, backs Quantum Motion's silicon-CMOS spin qubit technology, which experts describe as a 'cleaner technical credential' in the competitive European quantum hardware landscape.

"This marks a pivotal moment for European quantum sovereignty," said Dr. Elena Voss, managing partner at Scaleup Europe Fund. "Quantum Motion's approach offers a scalable, manufacturable path that aligns with our strategic goal of building independent European capabilities."

What happened

The $160 million Series C round positions Quantum Motion among the best-funded quantum startups in Europe. The company specialises in qubits made from silicon-CMOS—a variant of the same technology used in conventional computer chips.

"Silicon spin qubits can leverage existing semiconductor fabrication plants, drastically reducing the cost and complexity of scaling up," explained Professor James Hanley, a quantum computing researcher at the University of Oxford not involved in the deal.

Background

Scaleup Europe Fund was created to provide late-stage capital to high-growth European deep-tech companies, filling a gap often called the 'scale-up valley of death.' The fund's first investment landing on a UK firm—despite Brexit—signals a pragmatic approach to technology leadership.

Quantum Motion, spun out from University College London and Oxford in 2017, has raised over $200 million to date. Its silicon-CMOS qubits operate at temperatures above 1 Kelvin, reducing reliance on complex cryogenic systems.

"This technology could be the key to fault-tolerant quantum computers that actually leave the lab," said Dr. Li-Wei Chen, a senior analyst at Quantum Insider. "But $160 million must be deployed wisely to overcome yield and error-rate challenges."

What this means

The deal strengthens the EU's push to secure quantum capabilities within the bloc and allied countries like the UK. It also validates silicon-based qubits as a credible alternative to superconducting or trapped-ion approaches.

For European policymakers, the investment underscores a willingness to back UK tech despite political tensions. For the broader quantum industry, it sets a new benchmark for late-stage funding in Europe.

"We expect to see more crossover between EU funds and UK deep-tech," added Dr. Voss. "Talent and innovation don't respect borders—and neither should capital."
