    "abstract": "I prove the security of quantum key distribution against individual attacks\nfor realistic signals sources, including weak coherent pulses and\ndownconversion sources. The proof applies to the BB84 protocol with the\nstandard detection scheme (no strong reference pulse). I obtain a formula for\nthe secure bit rate per time slot of an experimental setup which can be used to\noptimize the performance of existing schemes for the considered scenario.",
