Abstract
Ground-satellite quantum key distribution (QKD) is a feasible way to implement global-scale quantum communication. Herein we propose an approach to dynamically compensate the polarization of the photons when passing through the optical telescope used in ground-satellite QKD. Our results experimentally demonstrate that the fidelity of any polarization state after dynamic compensation can be achieved by more than 99.5%, which fulfills the requirements of ground-satellite QKD.
