Quantum information theory and quantum many-body theory (Jens Eisert)

Our leading group is concerned with research in quantum information theory, condensed matter theory and the intersection between the fields.

- We ask what information processing tasks are possible using single quantum systems as carriers of information. We think about the mathematical-theoretical foundations of quantum information, specifically about the theory of entanglement and questions of tomography, but also about ways of realizing topological quantum computing.
