    "abstract": "Security formulas of quantum key distribution (QKD) with imperfect resources\nare obtained for finite-length code when the decoy method is applied. This\nanalysis is useful for guaranteeing the security of implemented QKD systems.\nOur formulas take into account the effect of the vacuum state and dark counts\nin the detector. We compare the asymptotic key generation rate in presence of\ndark counts with that without.",
