Ultracold atoms in optical lattices provide an experimental platform to perform controlled single-particle operations in many-body systems. The UniRand experiment aims to leverage this control to study physics at the interface between condensed matter physics and quantum information science. One exciting avenue towards this goal are measurements in random bases using so-called random unitary protocols. They are predicted to give access to global density matrix properties and provide a general way of characterizing many-body systems in and out of equilibrium. We report on the progress of building a fermionic quantum simulator capable of realizing random unitaries with high repetition rates and a high-fidelity readout process. At present, the experiment demonstrates the use of 2D-MOT as a cold atom source, capable of loading with high rates into the 3D-MOT, and atom counting capability with single atom resolution. The envisaged system combines evaporative cooling in optical tweezer arrays followed by quantum state assembly in a tunable optical lattice. The readout process aims to reach single site resolution by using matter wave magnification and spin-resolved free-space imaging. The poster will summarize the current status and future prospects of the experiment.
