High-rate intercity quantum key distribution with a semiconductor single-photon source

High-rate intercity quantum key distribution with a semiconductor single-photon source Abstract Quantum key distribution (QKD) enables the transmission of information that is secure against general attacks by eavesdroppers. The use of on-demand quantum light sources in QKD protocols is expected to help improve security and maximum tolerable loss. Semiconductor quantum dots (QDs) are a promising building block for quantum communication applications because of the deterministic emission of single...
