Oxford Quantum Circuits raises £260m Series C led by Bullhound Capital to scale its quantum computing infrastructure

Bullhound Capital led the Series C financing, which stands as Europe's largest private quantum funding round.
Oxford Quantum Circuits builds superconducting quantum computers using proprietary 3D architecture designed for commercial data centres.
Oxford Quantum Circuits has raised £260m in a Series C funding round led by Bullhound Capital. The financing represents Europe's largest private quantum computing funding round to date.
The oversubscribed round saw participation from a broad group of investors including the British Business Bank, JPMorgan, and several returning backers. The capital will support the company as it expands its international footprint and accelerates its technology roadmap.
Based in the UK, the company deploys operational quantum systems directly into commercial data centres alongside classical infrastructure. The fresh funds arrive as the quantum computing sector shifts towards deployment and commercial scale.
From the founder
"Globally, it represents a clear shift in the market from long-term promise to near-term delivery in quantum computing. For OQC, this gives us the capital to scale internationally, advance our technology roadmap, and meet increasing demand from customers seeking secure, scalable access to quantum computing infrastructure."
Gerald Mullally
CEO at Oxford Quantum Circuits
Investor perspective
"OQC is building one of the most compelling quantum computing platforms globally, with the technology, infrastructure and customer focus required to scale. As quantum computing moves into global infrastructure, OQC is positioned to shape that transition."
