单光子探测器在量子通信和微光深度成像等新兴应用领域发挥着越来越重要的作用。单光子探测器的特性对系统性能有很大的影响,本报告将探讨单光子探测器在这些重要应用领域中的作用。我们将讨论GHz时钟量子密钥分配系统的实验系统性能,重点关注量子误码率,净比特率和传输距离与不同的探测器结构的问题,集中在单光子雪崩二极管探测器,但也检查超导超导晶体管为基础的结构。量子密钥分配系统的设计是环境鲁棒性和长期的系统运行的检查。还将讨论探测器性能在光子计数飞行时间三维成像中的作用。我们将描述一个现有的实验测试床系统设计公里测距,和最近的实验结果,从现场试验。该演示文稿将研究数据采集时间,光功率水平和最大范围的关键权衡。在这两个例子中,将提出实验演示,以探索未来的观点和设计目标。
Single-photon detectors play an increasing role in emerging application areas in quantum communication and low-light level depth imaging. The single-photon detector characteristics have a telling impact in system performance, and this presentation will examine the role of single-photon detectors in these important application areas. We will discuss the experimental system performance of GHz-clocked quantum key distribution systems focusing on issues of quantum bit error rate, net bit rate and transmission distance with different detector structures, concentrating on single-photon avalanche diode detectors, but also examining superconducting nanowire-based structures. The quantum key distribution system is designed to be environmentally robust and an examination of long-term system operation will be presented. The role of detector performance in photon-counting time-of-flight three-dimensional imaging will also be discussed. We will describe an existing experimental test bed system designed for kilometer ranging, and recent experimental results from field trials. The presentation will investigate the key trade-offs in data acquisition time, optical power levels and maximum range. In both examples, experimental demonstrations will be presented to explore future perspectives and design goals.
