| Research Abstract |
We consider the quantum error correction over the depolarizing channels with non-binary low-density parity-check (LDPC) codes defined over Galois field of size 2p. The proposed quantum error correcting codes are based on the binary quasi-cyclic CSS (Calderbank, Shor and Steane) codes. The resulting quantum codes outperform the best known quantum codes and surpass the performance limit of the bounded distance decoder.
