Photon-number-resolving decoy-state quantum key distribution
Photon-number-resolving decoy-state quantum key distribution
In this paper, a photon-number-resolving decoy-state quantum key distribution (QKD) scheme is presented based on recent experimental advancements. A new upper bound on the fraction of counts caused by multiphoton pulses is given, which seems inherent as long as weak coherent sources and high lossy channel are used. This implies …
