Harald Weinfurter

from Wikipedia, the free encyclopedia

Harald Weinfurter (born May 14, 1960 in Steyr ) is an Austrian physicist and university professor who deals experimentally with the fundamentals of quantum mechanics and quantum optics.

Weinfurter studied technical physics at the Vienna University of Technology from 1978 , where he obtained his diploma in 1983 and his doctorate in 1987, and completed his habilitation in 1996 at the University of Innsbruck ( Quantum Interferometry ). From 1988 to 1991 he was at the Hahn-Meitner-Institut in Berlin and from 1991 university assistant in Innsbruck, where he was in Anton Zeilinger's group . From 1996 to 1999 he was an APART research fellow at the Austrian Academy of Sciences. He has been Professor of Quantum Optics at the Ludwig Maximilians University in Munich since 1999 .

Weinfurter dealt, among other things, with quantum entanglement and quantum cryptography , where he and Christian Kurtsiefer are known for a record in the transmission of a bug-proof message over 23.4 km between Zugspitze and Karwendel in 2002.

In 1996 he received the Fritz Kohlrausch Prize and the Start Prize and in 2003 the Philip Morris Research Prize with Christian Kurtsiefer . In 2004 he was one of the recipients of the Descartes Prize for the IST-QuComm project, and in 2014 he received the Copernicus Prize . Weinfurter has been a "Fellow" at the Max Planck Institute for Quantum Optics , Garching, since 2010 .
