Physics:Quantum Hong-Ou-Mandel effect
The Hong-Ou-Mandel effect is a Book I topic in the Quantum Collection. It is a two-photon interference effect observed when identical photons enter the two input ports of a beam splitter. Instead of leaving separately, the photons tend to leave together in the same output mode, producing a dip in coincidence counts. The effect is a direct signature of photon indistinguishability and bosonic exchange symmetry. It is widely used to characterize single-photon sources, optical delays, entanglement generation, and multi-photon interference. It is also a building block for photonic quantum information experiments.
