Demonstrating the ability of the University of Bristol's 5GUK Test Network to host a quantum key distribution (QKD) secured network.

To accommodate the demands of an increasingly digital world, faster networks that are reliable and secure are needed. As part of the Quantum Communications Hub, members of Quantum Engineering Technology Labs and the High Performance Network Group of Smart Internet Lab at the University of Bristol showcased their expertise and innovation at the QKD over 5GUK launch on 03 September 2019. 

The team demonstrated the ability of the University of Bristol's 5GUK Test Network to host a quantum key distribution (QKD) secured network and to deliver dynamic QKD key exchange over end-to-end core, metro and access networks using open-source software developed by researchers in the group. There were demonstrations of the network, as well as QKD applications, ranging from securing national infrastructure to securing end-user transactions.
