Schematic of the experimental setup including a spectrally-multiplexed photon pair source, a VIPA-based demultiplexer for mapping spectral modes to distinct spatial channels, and a Tm3+:LiNbO3-based spectral filter: APD - avalanche photodiode; DDG - digital delay generator; SNSPD - superconducting nanowire single photon detector; AD - achromatic Doublet (focusing lens coupling the output beam into collection fiber).

Towards a spectrally multiplexed quantum repeater

Extended quantum networks are based on quantum repeaters that often rely on the distribution of entanglement in an efficient and heralded fashion over multiple network nodes. Many repeater architectures require multiplexed sources of entangled photon […]
