A number of applications in basic science and technology would benefit from high-fidelity photon-number-resolving photodetectors. While some recent experimental progress has been made in this direction, the requirements for true photon number resolution are stringent, and no design currently exists that achieves this goal. Here we employ techniques from fundamental quantum optics to demonstrate that detectors composed of subwavelength elements interacting collectively with the photon field can achieve high-performance photon number resolution. We propose a new design that simultaneously achieves photon number resolution, high efficiency, low jitter, low dark counts, and high count rate. We discuss specific systems that satisfy the design requirements, pointing to the important role of nanoscale device elements.

基于相干相互作用的纳米级高性能光子数分辨光电探测器的设计

高保真光子数解析光电探测器将使基础科学和技术领域的许多应用受益。尽管在此方向上已取得了一些最新的实验进展，但对真正的光子数分辨率的要求非常严格，并且目前尚无实现该目标的设计。在这里，我们使用基础量子光学的技术来证明由与光子场共同相互作用的亚波长元素组成的探测器可以实现高性能的光子数分辨率。我们提出了一种新设计，该设计可同时实现光子数分辨率，高效率，低抖动，低暗计数和高计数率。我们讨论了满足设计要求的特定系统，指出了纳米级器件元件的重要作用。
