探测单个光量子（单个光子）的能力在从天文学到量子光学的许多物理领域都受到重视。超导光子探测器在灵敏度、光谱范围和时间分辨率方面提供了卓越的性能。本文介绍了超导器件中光子吸收的基本物理性质。然后，我们介绍了用于可见光和红外波长光子计数的当代超导探测器技术的详细案例研究。最后，我们对这一令人兴奋的领域的未来发展进行了展望。
The ability to detect individual light quanta – single photons – is prized across many fields of physics from astronomy to quantum optics. Superconducting photon detectors offer exceptional performance in terms of sensitivity, spectral range and timing resolution. In this review, we introduce the underlying physics of photon absorption in superconducting devices. We then present detailed case studies of contemporary superconducting detector technologies for photon counting at visible and infrared wavelengths. We conclude with a perspective on future developments in this exciting area.
