| Abstract: | Based on the classical LDPC construction method and quantum error correction techniques,a construction method of quantum low-density-parity-check codes based on stabilizer codes is discussed method in this paper.We provide quantum code (12,3) obtained by our methed as example to verify this construction, together with a numerical simulation of the performance of quantum code (32,12) and quantum code (64,24)over the depolarizing channel. |
