Hong–Ou–Mandel effect dip is related to the states of the two photons formula_14 and formula_15 as If formula_17, then the visibility is equal to the purity formula_18 of the photons. In 2006, an experiment was performed in which two atoms independently emitted a single photon each. These photons subsequently produced the Hong–Ou–Mandel effect. The Hong–Ou–Mandel effect also underlies the basic entangling mechanism in linear optical quantum computing, and the two-photon quantum state formula_19 that leads to the HOM dip is the simplest non-trivial state in a class called NOON states. In 2015 the Hong–Ou–Mandel effect for photons was directly observed with spatial
