Abstract: The present invention relates to a method for combining and dividing a quantum channel which is refer to a polar quantum channel for generating a quantum bit (qubit) which achieves symmetric capacity even if some binary input discrete quantum channels are given. Current capacity is determined according to qubit input having the same probability. The polarization of the quantum channel is transmitted to rate 1 if a symmetric channel is close to one. Or if not, the polarization of the quantum channel is transmitted to rate 0. The polarization of the quantum channel is suitable for coding quantum error correction for partially transmitting quantum data through the channel.
