Fig. 5: The logical and physical topologies of the entanglement network.

a shows the logical entanglement topology. b shows a sketch of the physical topology of the fibre network, as detailed in Fig. 1 where link losses include all optical components between the entanglement source and the quantum measurement module, including loss associated with the q-ROADM.
