纠缠光子的量子干涉产生了大量经典物理学中没有对应的有趣现象。然而，由于量子光学的突出特性，量子干涉已被广泛研究，并提供了有用的工具，最终拓宽了超灵敏量子计量学的道路，从亚散粒噪声量子传感到高分辨率光谱学。特别是，量子干涉测量是一个必不可少的必要条件，用于提取有关光子敏感的生物和化学分子的结构和动力学的信息。本文综述了量子干涉计量技术的理论和实验进展沿着应用。本综述的范围包括Hong-Ou-Mandel干涉测量与时间分辨率，基于傅里叶变换的纠缠辅助吸收光谱，以及使用可调能量-时间纠缠光子的虚态光谱。
Quantum interferences of entangled photons have engendered tremendous intriguing phenomena that lack any counterpart in classical physics. Hitherto, owing to the salient properties of quantum optics, quantum interference has been widely studied and provides useful tools that ultimately broaden the path towards ultra-sensitive quantum metrology, ranging from sub-shot-noise quantum sensing to high-resolution optical spectroscopy. In particular, quantum interferometric metrology is an essential requisite for extracting information about the structure and dynamics of photon-sensitive biological and chemical molecules. This article reviews the theoretical and experimental progress of this quantum interferometric metrology technology along with their advanced applications. The scope of this review includes Hong–Ou–Mandel interferometry with ultrahigh timing resolution, entanglement-assisted absorption spectroscopy based on a Fourier transform, and virtual-state spectroscopy using tunable energy-time entangled photons.
