Entanglement of nanophotonic quantum memory nodes in a telecom network

https://www.nature.com/articles/s41586-024-07252-z ::: spoiler a bit of the abstract: ... By integrating efficient bidirectional quantum frequency conversion of photonic communication qubits to telecommunication frequencies (1,350 nm), we demonstrate the entanglement of two nuclear spin memories through 40 km spools of low-loss fibre and a 35-km long fibre loop deployed in the Boston area urban environment, representing an enabling step towards practical quantum repeaters and large-scale quantum networks. ... :::
