Quantum optics / Atomic physics

A secure method of encryption, quantum cryptography is one of the most important fields of application in quantum research. Using light photons in different quantum states, for example, it might at some stage be possible to make the transmission of information absolutely tap-proof. The fundamental research to enable such developments is done at the interface of nanophotonics and quantum optics – and in this field, Arno Rauschenbeutel is a world leader. He has managed to capture atoms close to the surface of glass fibres by passing light through extremely thin glass fibres with a diameter of less than the wavelength of light. The light that is emitted or absorbed by the fibre during oscillation captures and traps atoms. The insights gained from Rauschenbeutel’s experiments could lead to the development of novel optical sensors or tap-proof glass fibres. Born in Germany, the physicist who currently works at Vienna University of Technology (TU Wien) is invited to become an Alexander von Humboldt Professor at Humboldt-Universität zu Berlin and reinforce the new Center for Photonic Quantum Technologies in the Berlin-Adlershof Science and Technology Park.

Nominating University: Humboldt-Universität zu Berlin

Prof. Dr. Arno Rauschenbeutel

Born in Germany in 1971, Arno Rauschenbeutel is a professor and head of the group "Applied Quantum Physics" at the Atominstitut (ATI) at TU Wien in Austria. Before moving there in 2010, he held professorships in Mainz and Bonn and also worked in Paris, London and Düsseldorf. He has received various prestigious awards, including the European Science Foundation’s European Young Investigator Award in 2006 and a European Research Council ERC Consolidator Grant in 2014.
