A quantum key distribution testbed using a plug&play telecom-wavelength single-photon source

A quantum key distribution testbed using a plug&play telecom-wavelength single-photon source Deterministic solid state quantum light sources are considered key building blocks for future communication networks. While several proof-of-principle experiments of quantum communication using such sources have been realized, most of them required large setups—often involving liquid helium infrastructure or bulky closed-cycle cryotechnology. In this work, we report on the first quantum key distribution...
