    "abstract": "We apply the techniques introduced in [Kraus et. al., Phys. Rev. Lett. 95,\n080501, 2005] to prove security of quantum key distribution (QKD) schemes using\ntwo-way classical post-processing as well as QKD schemes based on weak coherent\npulses instead of single-photon pulses. As a result, we obtain improved bounds\non the secret-key rate of these schemes.",
