    "abstract": "In this paper, a photon-number-resolving decoy state quantum key distribution\nscheme is presented based on recent experimental advancements. A new upper\nbound on the fraction of counts caused by multiphoton pulses is given. This\nupper bound is independent of intensity of the decoy source, so that both the\nsignal pulses and the decoy pulses can be used to generate the raw key after\nverified the security of the communication. This upper bound is also the lower\nbound on the fraction of counts caused by multiphoton pulses as long as faint\ncoherent sources and high lossy channels are used. We show that Eve\u0027s coherent\nmultiphoton pulse (CMP) attack is more efficient than symmetric individual (SI)\nattack when quantum bit error rate is small, so that CMP attack should be\nconsidered to ensure the security of the final key. finally, optimal intensity\nof laser source is presented which provides 23.9 km increase in the\ntransmission distance. 03.67.Dd",
