【Abstract】 In this paper,the practical quantum key distribution is studied.By using the EPR pair,a photon-number-resolving quantum key distribution protocol is presented.The analysis and calculation show that such protocol can not only increase the distance of the secure key transmission but also can make the experiment easy.更多还原
