OQC

OQC (Oxford Quantum Circuits) is a British quantum-computing company building superconducting systems. In June 2026 it raised an oversubscribed £260 million Series C led by Bullhound Capital — Europe's largest quantum private round — with the British Business Bank anchoring at £100 million. It was the fourth European quantum round above $100 million in a year that had already surpassed all of 2025, funding global deployment toward fault-tolerant systems for finance, defence and security.
