초록
Provided is a polarization coding quantum cryptography system. The quantum cryptography includes a light source, a quantum channel, an optical path selector, and a path-dependent polarization selector. The light source generates a signal light. The quantum channel is used as a path to transmit the signal light to a receiver unit. The optical path selector is disposed between the light source and the quantum channel to transmit the signal light to one of a plurality of propagation paths. The path-dependent polarization selector is disposed between the optical path selector and the quantum channel. Herein, the path-dependent polarization selector is configured to determine the polarization direction of the signal light according to the propagation path of the signal light.
