Formally known as Pierre and Marie Curie University (French: Université Pierre-et-Marie-Curie; abbreviated UPMC) or University of Paris VI, now Sorbonne University following a merger between large universities in Paris, is a public research university that was established in 1971 following the division of the University of Paris (Sorbonne). It is a principal heir to Faculty of Sciences of the Sorbonne (French: Faculté des sciences de Paris), UPMC is the largest scientific and medical complex in France, active in many fields of research with scope and achievements at the highest level. It has more than 125 laboratories, most of them in association with the ‘’Centre national de la recherche scientifique’’ (CNRS). The Laboratoire Kastler Brossel is a major player in the field of quantum physics. The Multimode Quantum Optics team cover two main topics: Femtosecond Quantum Optics and Optical fiber networks. The main idea of the first research line is to merge the field of ultrafast optical frequency combs with the field of quantum optics with the goal of exploring new capabilities that arise from the interplay of the quantum properties of light at extreme timescales and over extremely broad spectra.
