London Quantum-Secured Metro Network
A commercial trial of a quantum-secured fibre network in London, run by BT with quantum key distribution equipment from Toshiba.
Project data last updated 11 October 2026
About this project
BT and Toshiba launched the network on 26 April 2022 after announcing it in October 2021. BT runs the network over Openreach fibre and Toshiba supplies the quantum key distribution hardware and key management software. EY was the first customer, linking sites in Canary Wharf and near London Bridge.
In July 2023 HSBC joined, linking its Canary Wharf headquarters to a data centre in Berkshire about 62 km away. AWS took part in that trial with edge computing services.
