摘要
The secure key rates of decoy-state quantum key distribution (QKD) using the heralded single-photon source (HSPS) are recalculated in the case of intensity fluctuations. By numerical simulations, we show that the HSPS is a good source for decoy-state QKD experiments not only because it has larger upper bound of transmission distance than the usual weak-coherent source (WCS) but also because it is more robust against intensity fluctuations than the WCS.
