论文摘要
量子网络的发展取决于混合系统的进步，其中包括地面通信。但是，环境的大气湍流对光学量子链路构成了严重的挑战。在本文中，我们概述了使用完全和部分空间相干的泵束对大气湍流对纠缠光子对重合检测的影响的理论和实验研究。空间光调节器用kolmogorov模型编码，以模仿大气湍流强度。结果表明，使用部分空间相干泵产生的光子对比完全空间相干的泵梁产生的光子对更适合不同的大气湍流强度。
The development of a quantum network relies on the advances of hybrid systems which includes ground to ground communication. However, the atmospheric turbulence of the environment poses a severe challenge to the optical quantum link. In this paper, we outline a theoretical and experimental investigation of the influence of atmospheric turbulence on the coincidence detection of the entangled photon pairs using a fully and partially spatially coherent pump beam. A spatial light modulator is encoded with Kolmogorov model to mimic the atmospheric turbulence strength. The results show that the photon pairs generated using a partially spatially coherent pump are more robust towards varying atmospheric turbulence strengths than the photon pairs produced by a fully spatially coherent pump beam.
