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

Research

Hans Briegel has developed fundamental concepts in the field of
quantum information Quantum information is the information of the state of a quantum system. It is the basic entity of study in quantum information theory, and can be manipulated using quantum information processing techniques. Quantum information refers to both t ...

quantum computing A quantum computer is a computer that exploits quantum mechanical phenomena. On small scales, physical matter exhibits properties of wave-particle duality, both particles and waves, and quantum computing takes advantage of this behavior using s ...
and
quantum communication In quantum information theory, a quantum channel is a communication channel that can transmit quantum information, as well as classical information. An example of quantum information is the general dynamics of a qubit. An example of classical in ...
. 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. 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. 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 Quantum information science is a field that combines the principles of quantum mechanics with information theory to study the processing, analysis, and transmission of information. It covers both theoretical and experimental aspects of quantum phys ...
. The concept of the quantum repeater, presented by Hans Briegel and his colleagues in 1998, 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

; he opposes the notion that the laws of nature don't permit free will. He developed a theoretical model that he calls “projective simulation”, which allows for a rudimentary form of creative behavior for artificial agents.
