超导纳米线单光子探测器（SNSPD）在其演示20年后，已成为量子光子学以及许多其他光子匮乏应用不可或缺的工具。这项发明不仅导致了一个新兴的学术领域，具有广泛的应用范围，而且还引发了工业上的努力。目前最先进的SNSPD结合了联合收割机在宽光谱范围内的接近1的检测效率、低暗计数、短死区时间和皮秒时间分辨率。本观点讨论了SNSPD研究的重要里程碑和进展、新兴应用和未来挑战，并展望了将SNSPD提升到下一个水平所需的技术发展：光子计数、快速时间标记成像和多像素技术，该技术也与量子光子集成电路兼容。
Two decades after their demonstration, superconducting nanowire single-photon detectors (SNSPDs) have become indispensable tools for quantum photonics as well as for many other photon-starved applications. This invention has not only led to a burgeoning academic field with a wide range of applications but also triggered industrial efforts. Current state-of-the-art SNSPDs combine near-unity detection efficiency over a wide spectral range, low dark counts, short dead times, and picosecond time resolution. The present perspective discusses important milestones and progress of SNSPDs research, emerging applications, and future challenges and gives an outlook on technological developments required to bring SNSPDs to the next level: a photon-counting, fast time-tagging imaging, and multi-pixel technology that is also compatible with quantum photonic integrated circuits.
