Oxford Quantum Circuits raises $350M Series C

Oxford Quantum Circuits has raised a $350M Series C, making this one of the standout European deeptech funding stories of the day.

What happened

The UK quantum computing company secured fresh capital to keep building and deploying quantum systems. OQC has positioned itself around quantum infrastructure, including systems connected to partner data centres.

Why it matters

This is not just a shiny lab-science story. Quantum computing remains early, expensive, and technically difficult, but large rounds like this show investors are still willing to back long-horizon infrastructure bets.

For Europe, it is also a useful signal: the region wants credible companies in frontier computing, not just software apps built on top of someone else’s infrastructure.

The bigger picture

As AI workloads keep increasing demand for compute, investors are also looking at what comes after today’s GPUs. Quantum is not replacing classical compute tomorrow, but it is part of the broader race to own future computing platforms.
