Quantum computing in London

London’s quantum cluster joins serious hardware and algorithm companies to one of the world’s deepest pools of finance, cyber-security and AI expertise. ORCA Computing is building photonic systems in the capital, while Phasecraft develops quantum algorithms and Crypto Quantique brings quantum-derived security into silicon. Just as importantly, London puts these technologies close to demanding early adopters in banking, defence and enterprise computing, backed by specialist deep-tech investors and the UK’s national quantum programmes. That combination makes the city unusually strong at turning quantum science into commercial systems.
