Hans Jürgen Briegel (born 9 August 1962 in Ochsenhausen)[1] is a German theoretical physicist.

[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).

[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.

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.

He developed a theoretical model that he calls “projective simulation”,[11] which allows for a rudimentary form of creative behavior for artificial agents.
