BT, Toshiba roll out commercial quantum-secured network

BT and Toshiba have built the world’s first commercial quantum-secured metro network over standard fibre cables for EY, securely transmitting the consultancy’s data between sites in London Bridge and Canary Wharf.

The partners say the network is a major step forward for the commercialization of the technology and for the UK government’s ambition to be a ‘quantum-enabled’ economy.
