BT and Toshiba, along with EY launched the trial of a world first commercial quantum secured metro network. The infrastructure will be able to connect numerous customers across London, helping them to secure the transmission of valuable data and information between multiple physical locations over standard fibre optic links using quantum key distribution (QKD).
The network’s first commercial customer, EY, will use the network to connect two of its sites in London, one in Canary Wharf, and one near London Bridge.
BT will operate the network, providing a range of quantum-secured services including dedicated high bandwidth end-to-end encrypted links, delivered over Openreach’s private fibre networks, while Toshiba will provide quantum key distribution hardware and key management software.
In the network, QKD keys will be combined with the in-built ethernet security, based on public-key based encryption, which will enable the resultant keys to be used to encrypt the data.
George Freeman, Minister for Science, Research and Innovation, HM Government, commented: “I am very pleased to see the first trial by BT and Toshiba of a commercial quantum secured metro network, which represents significant progress towards achieving our ambition to make the UK a quantum-enabled economy. This is the kind of innovation that helps cement the UK as a global innovation economy in the vanguard of discovering, developing and commercially adopting transformational technology with real societal benefits.”
