The 2026 City Quantum & AI Summit will take place on Oct. 7 at London’s Mansion House, bringing together leaders from government, defense, industry, academia and finance under the theme “Connections in Chaos.” The agenda features discussions on defense, cybersecurity, life sciences, space, finance and the convergence of quantum computing and AI, with speakers from organizations including NATO, Multiverse Computing, Cleveland Clinic, GSK, NVIDIA, Oxford Quantum Circuits, Google DeepMind and the London Stock Exchange. Organizers say the summit is designed to strengthen collaboration across industries and allied nations as governments and businesses increase investment in quantum technologies and AI to address economic competitiveness, scientific innovation and national security challenges. Building on its 6-year tradition, the one-day conference will include remarks from Alderman.
