Telecom Quantum Memory over 1 μs in Nanophotonic Lithium Niobate
Nanophotonic quantum memory is a vital component for scalable quantum information processing for quantum computing, networking, and sensing applications. We store single-photon-level telecom-band optical pulses for more than 1 μs using an atomic frequency comb in erbium-doped thin-film lithium niobate (TFLN), well be...
