Towards Simulations of Quantum Systems in Ion Traps — •Axel Friedenauer, Hector Schmitz, Lutz Petersen, Steffen Kahra, Günther Leschhorn, and Tobias Schätz — MPQ Garching

We report on the progress of building a quantum simulator or analog quantum computer designed to simulate quantum mechanical systems as e.g. quantum spin models, the Hubbard model or quantum random walks. Using hyperfine levels of Magnesium ions aligned in a linear chain in a Paul trap and applying optical dipole forces we are able to taylor interactions between these and control coupling strengths. Thus we can adapt our simple system to many interesting quantum single or many-body systems. We recently demonstrated ground-state cooling and are now heading for simulations with a single ion.
