Abstract

The polarization tracking principle is analyzed by using a half-wave plate in satellite quantum key distribution and the polarization 'zero' direction can be corrected by rotation of the half-wave plate. The transforms of six photon polarization states in three conjugative bases are given and the quantum key coding principle based on the polarization tracking is analyzed for the BB84 protocol and B92 protocol.
