2021 arXiv   pre-print
We build two nodes separated by 3.5 m, each contains a polarization-entangled photon-pair source and a solid-state quantum memory.  ...  Due to the inevitable loss in communication channels, the distance of entanglement distribution is limited to approximately 100 km on the ground.  ...  The overall storage performance (efficiency×time×bandwidth) is 7.8. To our knowledge, this is the best value reported so far for a wideband solid-state quantum memory [18, 50] .  ...
