Quantum key distribution uses quantum and classical channel to complete the growing of a secret key,because of imperfect devices and eavesdropping generate error,need to be corrected relying on classical channel.Use the hamming code in the block codes to achieve error-correcting,simulation analysis of the relationship between generation efficiency of key and the initial error rate,or generation efficiency of key and different codeword length.The results showed that at higher bit error rate,using shorter code,at lower bit error rate,using longer code,can improve the generation efficiency of key,the level of the bit error rate based on the estimated bit error rate.
