Recent advances in probing complex many body systems allow us to raise incisive questions about their dynamics, which are classically hard to compute. Studying the Fermi-Hubbard model using random unitary operators enables the observations of global properties of the density matrix of delocalized systems.
We report progress on building a fermionic quantum simulator capable of realizing random unitary operations. Such a high performance simulator requires a fast cycle time and a high fidelity readout process. We will achieve a fast cycle time by evaporative cooling in an optical tweezer array, followed by simultaneously loading into a tunable lattice. Our readout process will reach single site resolution employing matter wave magnification and spin-resolved free-space imaging. This will enable us to measure, for example, entanglement entropy, out-of-time-order correlators, and state tomography.
