Founded in the UK, OQC (Oxford Quantum Circuits) develops superconducting quantum computers designed for deployment in data centre environments for enterprise and government customers. The company has built a global footprint with systems already deployed across the UK, US, Japan, and Spain.

OQC’s technology is being adopted across sectors such as financial services, defence and national security where demand is growing for secure and scalable quantum infrastructure capable of solving problems beyond classical computing limits.

The new funding will accelerate OQC’s global expansion and advance its roadmap toward fault-tolerant, commercially useful quantum computing. The company also continues to align with the UK’s national strategy to lead in quantum technologies and advanced computing.

Gerald Mullally, CEO of OQC, said: “This is a coming-of-age moment for British quantum computing. It shows that British companies can play a leading role in a technology that will shape all our futures. 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.”
