Abstract (in Japanese) (See Japanese page) 
(in English) Quantum error correction is used in quantum computing and quantum communications to protect quantum information from quantum noise.
Quantum LDPC codes are efficiently decodable quantum error correcting codes defined by sparse parity-check equations.
CSS (Calderbank, Shor and Steane) codes are the most promising quantum error correcting coding scheme.
In this paper, we consider the quantum error correction over the depolarizing channels
with non-binary LDPC codes defined over Galois field of size $2^p$.
The resulting quantum codes outperform the best known quantum codes and
surpass the performance limit of the bounded distance decoder.
By increasing the size of the underlying Galois field, i.e., $2^p$, the error floors are considerably improved.
