| Abstract: | The decoy-state method of quantum key distribution(QKD) successfully solves the loophole of Photon-Number-Splitting attack and it also makes people to demonstrate QKD with a long distance. In this paper, we review the development of QKD, from BB84 protocol to the demonstration of three-intensity decoy-state method. We also explain how to get the final security key rate from the input parameters. |
