Abstract

I will present an introduction to the physics of ultracold atomic gases in optical lattices and consider their usefullness for quantum information. Due to unprecedented possibilities of control of physics parameters in such systems, ultracold gases may serve as Quantum Simulators to mimick models of condensed matter systems, or even of systems relevant for high energy physics. Ultracold gases themselves may allow for quantum information manipulations, quantum memories etc. Last, but not least quantum information methods help to simulate ultracold gases with classical computers.

My presentation will focus on some examples, such as frustrated ultracold gases, disordered ultracold gases and ultracold gases in \”atrificial\” magnetic fields.
