OU School of Community Medicine Medicine was founded in 1900 and is located in Oklahoma City, Oklahoma at the University of Oklahoma Health Sciences Center. In 1974, the OU College of Medicine opened a geographically separate, community-based clinical campus in Tulsa, approximately 100 miles northeast of the main campus. At the Tulsa campus, known as the OU Tulsa Schusterman Center, programs are affiliated with three community hospitals: Hillcrest Medical Center, Saint Francis Hospital, and St. John Medical Center. In 2008 a $50 million transformational gift from the George Kaiser Family Foundation allowed the OU College of Medicine Tulsa to change its focus. The gift established
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
