Abstract: To beat PNS attack, decoy state quantum key distribution (QKD) based oncoherent state has been studied widely. We present a decoy state QKD protocolwith modified coherent state (MCS). By destruction quantum interference, MCSwith fewer multi-photon events can be get, which may improve key bit rate andsecurity distance of QKD. Through numerical simulation, we show about 2-dBincrement on security distance for BB84 protocol.
