标题： Classical analogues of two-photon quantum interference

摘要： 啁啾脉冲干涉仪（CPI）在一个完全经典的系统中捕获了量子Hong-Ou-Mandel（HOM）干涉仪的计量优势。修改后的HOM干涉仪是许多具有开创性量子干涉效应的基础。在这里，相应的CPI修改使得首次观察到HOM峰值和量子拍频的经典模拟成为可能。它们还允许一种新的经典技术来生成相位超分辨率，其相干长度远长于激光光源的相干长度，类似于纠缠态中的双光子相干长度增加。 显示英文摘要

摘要： Chirped-pulse interferometry (CPI) captures the metrological advantages of quantum Hong-Ou-Mandel (HOM) interferometry in a completely classical system. Modified HOM interferometers are the basis for a number of seminal quantum-interference effects. Here, the corresponding modifications to CPI allow for the first observation of classical analogues to the HOM peak and quantum beating. They also allow a new classical technique for generating phase super-resolution exhibiting a coherence length dramatically longer than that of the laser light, analogous to increased two-photon coherence lengths in entangled states.
