Query: High Efficient Secret Key Distillation for Long Distance Continuous
  Variable Quantum Key Distribution   The continuous variable quantum key distribution is expected to provide high
secret key rate without single photon source and detector, but the lack of the
secure and effective key distillation method makes it unpractical. Here, we
present a secure single-bit-reverse-reconciliation protocol combined with
secret information concentration and post-selection, which can distill the
secret key with high efficiency and low computational complexity. The
simulation results show that this protocol can provide high secret key rate
even when the transmission fiber is longer than 150km, which may make the
continuous variable scheme to outvie the single photon one.
