Anton Zeilinger, born 20 May 1945, is an Austrian quantum physicist working on fundamental aspects of quantum science with focus of matter waves and quantum entanglement and pioneering possible applications, at the University of Vienna and the Austrian Academy of Sciences. Together with Alain Aspect and John F. Clauser he was awarded the Nobel Prize in Physics 2022 "for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science". In the 1970s, Zeilinger worked in Neutron Physics at the Atominstitut and at the Massachusetts Institute of Technology Neutron Diffraction Laboratory. In 1979, he qualified as a “Dozent” at the Vienna University of Technology. In 1981 Zeilinger returned to MIT in 1981 to the physics faculty until 1983. Between 1983 and 1990 he was associate professor at the Vienna University of Technology. In that time he became interested in quantum entanglement and initiated together with Greenberger and Horne the concept of multi particle entanglement. In 1990 he became the Chair of Experimental Physics at the University of Innsbruck. His many experiments on entanglement with photons include quantum cryptography, quantum dense coding, quantum state teleportation and the realization of three- and four-photon entanglement. In 1999 he became the Chair of Experimental Physics at the University of Vienna where he pioneered many experiments including the interference of large molecules starting with buckyballs, tests of quantum nonlocality, and the first realization of quantum gates for future quantum computers. He was also, between 2004 and 2013, scientific director of the Institute for Quantum Optics and Quantum Information in Vienna which he helped to create between 2004 and 2013. In Vienna he did experiments of tests of Bell's inequality including cosmic sources of randomness, and quantum communication via satellites. He also pioneered a number of basic procedures for optical quantum communication. Zeilinger became professor emeritus at the University of Vienna in 2013 where he still works on the foundations of quantum physics. His visiting appointments include the Technical University Munich, the Humboldt University Berlin, Oxford University and the Collège de France. He was president of the Austrian Academy of Sciences from 2013 till 2022. Anton Zeilinger is a member of numerous academies including the Slovak Academy of Sciences and holds several honorary professorships and honorary doctorates. Besides the Nobel Prize in Physics his awards and prizes include the German Order Pour le Mérite, the Order of Merit of Austria, the Wolf Prize (Israel), the Inaugural Isaac Newton Medal of the Institute of Physics, the John Stewart Bell Prize for Research on Fundamental Issues in Quantum Mechanics and their Applications, the Micius Quantum Prize and the King Faisal Prize.
