    "abstract": "The continuous variable quantum key distribution is expected to provide high\nsecret key rate without single photon source and detector, but the lack of the\nsecure and effective key distillation method makes it unpractical. Here, we\npresent a secure single-bit-reverse-reconciliation protocol combined with\nsecret information concentration and post-selection, which can distill the\nsecret key with high efficiency and low computational complexity. The\nsimulation results show that this protocol can provide high secret key rate\neven when the transmission fiber is longer than 150km, which may make the\ncontinuous variable scheme to outvie the single photon one.",
