A Compact Optical Lattice Quantum Simulator for Random Unitary Observables — •Naman Jain and Philipp Preiss — Max Planck Institute of Quantum Optics, Garching, Germany

The recent advances in probing complex quantum many-body systems at the level of single constituents allow us to pose incisive questions regarding the dynamics of such systems. Combining approaches from quantum information theory with state-of-the-art quantum simulation techniques may lead to new ways of characterizing itinerant quantum systems more generally. We pursue this in our project UniRand by realizing a new, widely applicable approach to measuring global quantum state properties in a system of ultracold atoms in an optical lattice - using random unitary operations. The strategy promises an entirely new toolbox for state characterization and device verification. To this end, we are developing a new, compact apparatus for the preparation of small-scale fermionic quantum gases in optical lattices with short cycle times. The design features a 2D MOT atomic source, a nanocoated glass cell and high-resolution imaging. Here, we report on the progress of this new experimental setup.
