Abstract: Since quantum secure communication cannot avoid the influence of noise in the transmission process, there will always be the problems of bit loss and bit reversal after the transmission is completed. In order to solve the problem of error information, stable code was used to encode quantum information, and the information was corrected through the classical calibration matrix of information channel transmission error correction after the completion of the transfer, which overcame the bit flip problem caused by channel noise, the accuracy of quantum information transmission had corresponding improvement, the security of quantum information transmission was also guaranteed, which verified the feasibility and effectiveness of the algorithm.

摘要： 由于量子保密通信在传输过程中无法避免噪声对其的影响，在传输完成以后，总会出现比特丢失、比特翻转的问题.为了解决信息出错问题，利用稳定子码对量子信息进行编码，并在传输完成以后通过经典信道传输校验矩阵对信息进行纠错，克服了因信道噪声而引起的比特翻转问题，量子信息传输的准确率也有相对应的提升，量子信息传输的安全性也得到了保障，从而验证了本算法的可行性和有效性.
