为了使加密系统中两个合法用户Alice和Bob从量子信道传送的相关的高斯连续变量X和Y中获取出密钥,通过一个理想公共授权信道传送部分信息进而从不一致的X和Y中得到一致的二进制密钥,这一过程称为协调。本文在样条纠错(Sliced Error Correction,SEC)和多级编码/多路译码(Multi Level coding/Multi Stage Decoding,MLC/MSD)方案的基础上,构建了一套以Turbo纠错码为基础的连续变量量子密钥分发系统的反向数据协调方案。提出了以Turbo码的校验比特流为协调信息的Slepian-Wolf编译码方案。仿真结果表明可在信道信噪比7dB以上实现20000个连续变量序列的协调。 In order for the two legitimate users Alice and Bob in the encryption system to obtain the key from the related Gaussian continuous variables X and Y transmitted by the quantum channel, part of the information is transmitted through an ideal common grant channel to be consistent from the inconsistent X and Y The binary key, this process is called coordination. Based on the Sliced ​​Error Correction (SEC) and Multi Level Coding / Multi-stage Decoding (MLC / MSD) schemes, a set of Turbo error- Reverse Data Coordination Scheme for Basic Continuous Variable Quantum Key Distribution System. A Slepian-Wolf codec with Turbo code parity bit stream as coordination information is proposed. The simulation results show that the coordination of 20000 continuous variable sequences can be realized above 7dB channel signal to noise ratio.
