摘要:

InGaAs/InP单光子雪崩二极管(SPAD)是实现高速量子密钥分发(QKD)的关键器件。我们首次开发了一种紧凑、稳定且用户友好的桌面InGaAs/InP单光子探测器系统,其工作频率为1.25 GHz,完全集成了控制和优化SPAD性能的功能。我们表征了探测器系统的关键参数,并测试了系统连续运行75小时的长期稳定性。该探测器系统可以大大提高QKD的性能,我们目前的工作为实际的高速QKD应用铺平了道路。

英文摘要:

InGaAs/InP single-photon avalanche diodes (SPADs) working in the regime of GHz clock rates are crucial components for the high-speed quantum key distribution (QKD). We have developed for the first time a compact, stable and user-friendly tabletop InGaAs/InP single-photon detector system operating at a 1.25 GHz gate rate that fully integrates functions for controlling and optimizing SPAD performance. We characterize the key parameters of the detector system and test the long-term stability of the system for continuous operation of 75 hours. The detector system can substantially enhance QKD performance and our present work paves the way for practical high-speed QKD applications.
