Hong-ou-mandel hom effect

Web术语“双光子干涉”是量子光学发展过程一个不恰当的使用。 在普通量子力学中、英国学者狄拉克 (Paul A. M. Dirac)曾经深刻地指出了（光）干涉之实质性图景：光子只与自己干涉 (A single photon wavepacket can only interfere with itself)。 事实表明，在后来的EPR实验、两光子纠缠态技术、多光子纠缠技术，以及量子光学等诸多领域中，所谓的干涉都没有突 … Web12 apr. 2024 · Hong–Ou–Mandel (HOM) interference—the bunching of indistinguishable photons at a beamsplitter—is a staple of quantum optics and lies at the heart of many quantum sensing approaches and recent optical quantum computers.
