ZHOU Yuan-yuan,ZHOU Xue-jun.SARG04 decoy-state quantum key distribution based on an unstable source[J].Optoelectronics Letters,2011,7(5):389-393 SARG04 decoy-state quantum key distribution based on an unstable source Author Name Affiliation ZHOU Yuan-yuan  Electronic Engineering College,Naval University of Engineering；  ZHOU Xue-jun  Electronic Engineering College,Naval University of Engineering；  Abstract:       A three-state protocol for the SARG04 decoy-state quantum key distribution(QKD)based on an unstable source is presented. The lower bound to the secure key generation rate is derived without using the basic hypothesis of the original decoy-state idea.The three-state SARG04 decoy-state protocol with an unstable parametric down-conversion source is considered in the simulation.The simulation results show that the protocol in this paper with an unstable source gives a key generation rate that is clo...
