Hans Jürgen Briegel (born 9 August 1962 in Ochsenhausen)[1] is a German theoretical physicist. He is Full Professor at the University of Innsbruck and conducts research in the field of quantum physics and quantum information.[2]

Biography[edit]

Briegel studied physics and philosophy at the Ludwig-Maximilian University Munich (1983-1990, terms 1986–1987 at the University of Edinburgh).[1] In 1990 he graduated with a diploma, and in 1994 he completed the PhD program (thesis title: The Jaynes-Cummings Model with Dissipation and its Application for the Dynamics of Microscopic Masers and Lasers).[3] He worked as Research Associate at the Texas A&M University and as Postdoctoral Fellow at Harvard University and the University of Innsbruck.[1] During that time he was also visiting scientist at Harvard-Smithsonian Center for Astrophysics. In 1997 he became Research Associate at the University of Munich and after his habilitation in 2002 (Quantum Information and Computer) he became Associate Professor (German: Privatdozent). In 2003 he was offered a Chair in Theoretical Physics at the University of Düsseldorf, which he declined. In the same year he accepted the post as Full Professor at the University of Innsbruck and as a Scientific Director at the Institute for Quantum Optics and Quantum Information at the Austrian Academy of Sciences.[4] Among other institutions, he has lectured and researched as visiting professor at the University of Bristol, UK, and the Tsinghua University, Beijing, China.[5] Hans Briegel is married and has two children.

Research[edit]

Hans Briegel has developed fundamental concepts in the field of quantum information, quantum computing and quantum communication. In 2001, together with Robert Raussendorf, he introduced the concept of a one-way quantum computer or measurement-based quantum computer model, which presented a new paradigm for building a quantum computer.[6] According to Thomson Reuter's analysis, the publication of this work is the second most-often cited publication in the field of quantum computing research in the first decade of the 21st century.[7] Together with his work in cluster and graph states, it led to a completely new understanding of entanglement as a resource for quantum information processing. The concept of the quantum repeater, presented by Hans Briegel and his colleagues in 1998,[8] plays an important role in quantum communication.

In recent years Hans Briegel has explored topics bordering on other scientific fields: He has investigated whether entanglement states also exist in biological systems, for example in the magnetic compass of migratory birds.[9] Briegel has also published work relating to the topic of agency and free will;[10] he opposes the notion that the laws of nature don't permit free will. He developed a theoretical model that he calls “projective simulation”,[11] which allows for a rudimentary form of creative behavior for artificial agents.
