论文摘要
目前，可用的单光子检测器的时间分辨率有限（几次二秒）限制了单光子的超快检测。光学门提供了更快的时间分辨率，但到目前为止，它们主要用于发射器的集合。在这里，我们通过半分析模型证明，在集中照明下以GHz速率以GHz速率，可以使用量子量发射器的超快时间分辨检测。该技术提供了子秒的时间分辨率，同时将门效率保持在85 \％左右。这些发现为对单个量子发射器的超快动力学的未来实验研究奠定了基础，对量子纳米光子学和分子物理学有影响
The ultrafast detection of single photons is currently restricted by the limited time resolution (a few picoseconds) of the available single-photon detectors. Optical gates offer a faster time resolution, but so far they have been mostly applied to ensembles of emitters. Here, we demonstrate through a semi-analytical model that the ultrafast time-resolved detection of single quantum emitters can be possible using an optical-Kerr-shutter (OKS) at GHz rates under focused illumination. This technique provides sub-picosecond time resolution, while keeping a gate efficiency at around 85 \%. These findings lay the ground for future experimental investigations on the ultrafast dynamics of single quantum emitters, with implications for quantum nanophotonics and molecular physics
