摘要: We propose the use of linear codes with low-density generator matrix in context error correction over different quantum channels. The basic idea is to construct a Calderbank-Shor-Steane (CSS) code based on and parity-check an LDGM code, applying row operations both matrices achieve desired rate. Decoding performed iterative manner, using message passing corresponding graphs. proposed allow greater flexibility are easier design than existing sparse-graph codes, while leading better performance.
