    "abstract": "We propose a practical decoy state method with heralded single photon source\nfor quantum key distribution (QKD). In the protocol, 3 intensities are used and\none can estimate the fraction of single-photon counts. The final key rate over\ntransmission distance is simulated under various parameter sets. Due to the\nlower dark count than that of a coherent state, it is shown that a 3-intensity\ndecoy-state QKD with a heralded source can work for a longer distance than that\nof a coherent state.",
