    "abstract": "In practical quantum key distribution (QKD), weak coherent states as the\nphoton sources have a limit in secure key rate and transmission distance\nbecause of the existence of multiphoton pulses and heavy loss in transmission\nline. Decoy states method and nonorthogonal encoding protocol are two important\nweapons to combat these effects. Here, we combine these two methods and propose\na efficient method that can substantially improve the performance of QKD. We\nfind a 79 km increase in transmission distance over the prior record using\ndecoy states method.",
