摘要: 该文给出了 型量子卷积码的一般结构，并计算得到其稳定子， 算子与 算子的标准型，重点讨论了这类码的编译码实现方法，描述了其编译码网络。 型量子卷积码的编译码过程只涉及Hadamard操作与控制非操作，因此编译码复杂度低，网络结构非常简单。Abstract: A general structure of CSS-type quantum convolutional codes is presented. The standard form of stabilizers, operators and operators are also given. Encoding and decoding of the codes are discussed with emphasis and corresponding networks are described. Only Hadamard and controlled NOT operations are involved in the whole process of encoding and decoding CSS-type quantum convolutional codes, so simple networks are obtained with low complexity.
