Abstract

Quantum networks have begun to connect many users together with Quantum Key Distribution links. We present a scalable, full mesh, polarisation entanglement-based quantum network without trusted nodes. We discuss our progress towards building a dynamic quantum network with more users, long distance (≈50 km) links and improved polarisation stability in the optical fibres. Lastly, minimising the resource overhead and optimising the network control based on end-user requirements are important features we are incorporating into our network.
