    "abstract": "We discuss the potential of quantum key distribution (QKD) for long distance\ncommunication by proposing a new analysis of the errors caused by dark counts.\nWe give sufficient conditions for a considerable improvement of the key\ngeneration rates and the security thresholds of well-known QKD protocols such\nas Bennett-Brassard 1984, Phoenix-Barnett-Chefles 2000, and the six-state\nprotocol. This analysis is applicable to other QKD protocols like Bennett 1992.\nWe examine two scenarios: a sender using a perfect single-photon source and a\nsender using a Poissonian source.",
