Abstract :
We study the error floor performance of a proposed family of LDGM-based quantum codes. LDGM-based quantum codes are Calderbank-Shor-Steane (CSS) codes based on the generator and parity-check matrices of a classical LDGM code. Decoding is performed in an iterative manner, by applying message passing over the corresponding graphs. The proposed codes allow greater flexibility and are easier to design than existing sparse-graph CSS quantum codes, while leading to better performance.
