Field trial of dynamic DV-QKD networking in the SDN-controlled fully-meshed optical metro network of the Bristol City 5GUK test network

Abstract

We demonstrate for the first time a field trial of a fully meshed metro network with dynamic QKD networking capabilities across four optical network nodes in the 5GUK Test Network, where the DV-QKD quantum channels co-exist with classical channels and are dynamically switched and rerouted utilising QKD-aware SDN control.
