Abstract:

Free-space quantum communication is one of the best ways to realize the global quantum communication network. In the process of free-space quantum communication, the photon polarization states are widely utilized for information encoding and communicating while the polarization states should be preserved. Five kinds of aspects are reviewed which have impact on the photon polarization states in free-space quantum communication. The corresponding physical mechanism and investigation methods are analyzed. Positive effect is shown by study of photon polarization states variation and compensation.
