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.
