Ou Reang Ov District part of Kampong Cham. The Ou Reang Ov district governor reports to His Excellency, the Governor of Tboung Khmum. The following table shows the villages of Ou Reang Ov district by commune. The district is subdivided into 7 communes ("khum") and 141 villages ("phum"). According to the 1998 Census, the population of the district was 82,806 persons in 16,940 households in 1998. With a population of over 80,000 people, Ou Reang Ou district has one of the smaller district populations in Tboung Khmum province.

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
