摘　　要：Continuous-variable quantum key distribution（CVQKD）[1-7]allows two remote parties（Alice and Bob）to share a secret key,even in the presence of an eavesdropper（Eve）with unlimited computational power[8-17].While,a highly efficient reconciliation protocol[18-21]is crucial in a CVQKDsystem, which can not only extract the errorless secret keys, but also provide a promising way to achieve a long distance CVQKD at a low signal-to-noise ratio （SNR）.Continuous-variable quantum key distribution(CVQKD)[1-7]allows two remote parties(Alice and Bob)to share a secret key,even in the presence of an eavesdropper(Eve)with unlimited computational power[8-17].While,a highly efficient reconciliation protocol[18-21]is crucial in a
