    "abstract": "In this paper, a new decoy-state scheme for quantum key distribution with\nparametric down-conversion source is proposed. We use both three-intensity\ndecoy states and their triggered and nontriggered components to estimate the\nfraction of single-photon counts and quantum bit-error rate of single-photon,\nand then deduce a more accurate value of key generation rate. The final key\nrate over transmission distance is simulated, which shows that we can obtain a\nhigher key rate than that of the existing methods, including our own earlier\nwork.",
