The physical layer consists of a broadband source of bipartite polarisation entanglement that is multiplexed and distributed to several users via one fibre each. In the entanglement distribution layer, polarisation entangled states are distributed to, and measured by each user. In the communication layer, they perform classical communication to generate the QKD keys, and execute the anonymous protocols described in this paper.
