Abstract

Aiming at the transmission of polarization encoded single photons in turbulent atmosphere, the random turbulence is modeled as atmospheric bubbles with various refractive indexes so as to conceive the propagation process of single photon using geometric optics. The fluctuation of photon transmission ratio k has been quantitatively calculated which is revealed as the relationship between transmission ratio and incident angle or turbulence scale. Based on that, the quantum bit error rate(QBER) and polarization fidelity of single photons are analyzed respectively which are both caused by the misalignment of polarization state after continuous refractions. Then the three dimensional relationship of k and polarization error rate Q are simulated with random incident angle or turbulence scale.
