| Abstract: | CSS code is a simple,efficient quantum error correction code construction,and has been found applications in construction of varieties of quantum codes,so far.In this paper,we propose a new construction method of quantum parity check matrix codes based on CSS by taking advantage of the method used in classical quasi-cyclic LDPC codes.Using quick encoding algorithm,we can obtain the quantum code based on this proposed method.At last,a quantum code(3,8)(16,6) is selected as the example to illustrate the proce... |
