| Summary: | To improve the performance of quantum decoding algorithm,a quantum probabilistic decoding algorithm（QPDA） based on the check matrix for quantum stabilizer codes was proposed.To achieve low error rates the error op-erator with the minimum quantum weight was chosen and to shorten the time of decoding a quantum standard array（QSA） was constructed before decoding.Comparing with the quantum maximum likelihood decoding algorithm,the QPAD improves the reliability of degenerate decoding due to uniform decoding methods for degenerate and non-degenerate codes,furthermore,has less complexity due to does not require pre-search the bases of vector space cor-responding to the error operator. |
