Quantum information and quantum many body theory (Jens Eisert)
Our group is concerned with research in quantum information theory, quantum optical implementations of quantum information ideas, and quantum many-body theory.
We ask what information processing tasks are possible using single quantum systems as carriers of information. On the one hand, we think about the mathematical-theoretical foundations of quantum information, specifically about the theory of entanglement. On the other hand, we are involved in identifying quantum optical realizations of such ideas, specifically using light modes or cold atoms in optical lattices.
A main emphasis of our theoretical research is also on the theory of quantum systems with many degrees of freedom, concerning their static properties, their efficient numerical simulation, as well as their quantum dynamics in non-equilibrium.
