A trackside fibre communication link in the Czech Republic has recently been upgraded to a quantum-secure connection using Toshiba’s multiplexed QKD technology. Despite heavy railway traffic in close proximity, the…

LONDON, 5 July: HSBC is the first bank to join BT and Toshiba’s quantum-secured metro network – connecting two UK sites using Quantum Key Distribution (QKD) to prepare its global…

This paper covers a commercially-ready QKD metro network built in London, complete with customer access tails and an aggregated central metro node, able to support multiple customers. The solution includes a full Key Management System; encrypted classical Ethernet data on the same fibre and a Data Communications Network (DCN) for full remote monitoring at BT’s Network Operations Centre (NOC).

This article describes experimental research studies conducted toward understanding the implementation aspects of high-capacity quantum-secured optical channels in mission-critical metro-scale operational environments using quantum key distribution (QKD) technology.
