Abstract

To study the long-distance free-space quantum communication links, we simulated, designed, and built a well characterized atmospheric turbulence simulator (ATS) with the Fried parameter and scintillation index ranging from weak to strong turbulence regimes. The ATS was integrated with a non-turbulent path to conduct quantum interferometric experiments such as the heralded single photon g^2 (τ) measurement, and Hong-Ou-Mandel measurements are in progress. We observed that g^2 (0) for heralded photon increased to 1 with moderate turbulence. A significant effect of strong turbulence is expected on the biphoton HOM interference with one photon propagating through free space and the other through the ATS.
