Free-space quantum key distribution(QKD) plays an important role in the global quantum network. However, free space channels suffer from the atmospheric turbulence and scattering effects of haze,fog, and dust, which significantly weaken the performance of QKD or even block the secure quantum ***, we prove the performance of QKD over a dynamic scattering channel can be enhanced significantly using a fast wavefront shaping technique. The system achieves on average 10-dB enhancement of quantum transmission efficiency and establishes a secure quantum link for QKD. Our work demonstrates the feasibility of QKD through free-space dynamic scattering channels and enhances the deployment capability of complex-channel QKD system.

在许多社交场景中,个体往往因为从众行为而改变自己的观点.为了探究从众行为对个体观点演化的影响,提出具有群体压力的改进Hegselmann-Krause (HK)模型.与已有模型不同,所提出模型中每个个体对其余个体的影响程度并不总是相同.首先,在此基础上,通过理论分析该模型的收敛性,并给出该模型的收敛时间及其与信任边界、群体压力大小等因素的关系;然后,考虑到群体中存在合作和对抗2种关系,进一步提出具有群体压力的改进符号HK模型,验证该模型的收敛性,并给出其收敛时间以及与信任边界、群体压力大小等因素的关系;最后,仿真分析信任边界和群体压力对所提出2种模型的观点演化过程和收敛时间的影响,并验证所提出模型的有效性.结果表明,信任边界与群体压力越大,群体内个体的观点收敛越快.
