“…Recently, reconfigurable and flexible entanglement networks were established with wavelength selective switches (WSS), where adaptive bandwidth management was performed to satisfy the dynamic connection demands of distant users [ 35 , 36 , 37 , 38 , 39 , 40 , 41 ]. Therefore, the entanglement routing with active wavelength multiplexing schemes is desiderated for constructing entanglement distribution networks with various topologies [ 42 , 43 , 44 , 45 ]. In the meantime, existing quantum routing schemes [ 2 , 46 , 47 , 48 , 49 , 50 , 51 , 52 ] are mainly focused on trusted node networks and quantum memory-assisted networks, and cannot be applied to quantum entanglement distribution networks, where time division multiplexing (TDM) and wavelength division multiplexing (WDM) techniques need to be adopted to forward entangled photons.…”
