摘要

Hong-Ou-Mandel （HOM）效应是一种有效的双光子干涉现象，是量子光学的基石，也是线性光学量子信息处理的重要工具。虽然HOM效应已经在理论和实验上对各种光子量子态进行了广泛的研究，特别是在光谱域，但在任意空间模式测量方案下，其对结构光子（具有复杂空间轮廓的光子）的行为的详细概述仍然缺乏。本教程旨在通过对结构光子的HOM效应进行全面的理论分析来填补这一空白，包括对量子干涉结果的任意模式投影。本教程还提供了不同测量条件下HOM可见性的解析式封闭表达式。

Tutorial: Hong–Ou–Mandel interference with structured photons

The Hong–Ou–Mandel (HOM) effect, an effective two-photon interference phenomenon, is a cornerstone of quantum optics and a key tool for linear optical quantum information processing. While the HOM effect has been extensively studied both theoretically and experimentally for various photonic quantum states, particularly in the spectral domain, detailed overviews of its behaviour for structured photons – those with complex spatial profiles – under arbitrary spatial mode measurement schemes are still lacking. This tutorial aims to fill this gap by providing a comprehensive theoretical analysis of the HOM effect for structured photons, including an arbitrary mode projection on quantum interference outcomes. The tutorial also provides analytical, closed-form expressions of the HOM visibility under different measurement conditions.
