Oxford Quantum Circuits raises £260m in European funding

A British quantum computing startup has secured a major investment to expand its global operations and advance its technology. Oxford Quantum Circuits (OQC) announced it has raised 260 million pounds, or approximately 350 million dollars, in a Series C funding round. The investment is described as the largest private capital raise for a quantum computing company in European history.

The funding round was led by Bullhound Capital and included significant participation from the British Business Bank, the UK government's economic development bank. The round was oversubscribed, with additional investment from a consortium of private and institutional backers, including Mastercard, COFIDES, and several university investment arms.

OQC develops and operates superconducting quantum computers designed for deployment in standard data center environments. The company stated the capital will be used to scale its international footprint, advance its technology roadmap, and meet growing customer demand for secure, scalable quantum infrastructure. The company has already established a global platform with systems deployed in the United Kingdom, the United States, Japan, and Spain.
