Hong–Ou–Mandel effect : ウィキペディア英語版 | Hong–Ou–Mandel effect The Hong–Ou–Mandel effect is a two-photon interference effect in quantum optics which was demonstrated by three physicists, C. K. Hong, Z. Y. Ou and Leonard Mandel in 1987 from the University of Rochester. The effect occurs when two identical single-photon waves enter a 50:50 beam splitter, one in each input port. When both photons are identical they will extinguish each other. If they become more distinguishable, the probability of detection will increase. In this way the interferometer can measure accurately bandwidth, path lengths and timing. ==Quantum-mechanical description==
