Fermionic quantum simulators provide a powerful platform for exploring the physics of high-temperature superconductivity, topological phases, and many-body dynamics - challenges that persist even with the advent of qubit-based quantum computing. Here, we present a high-repetition-rate fermionic quantum gas microscope optimized for rapid data acquisition. Fast cycle times below 4 seconds are achieved through high-power optical traps, rapid evaporative cooling, and efficient spin-resolved fluorescence imaging. These fast experimental cycles enable the collection of sufficient statistics to measure higher-order spin correlations, opening the door to systematic exploration of the phase diagram of the doped Fermi-Hubbard model. Looking ahead, planned upgrades to the apparatus will incorporate site-resolved addressing for precise single-particle control, enabling the investigation of quantum-information-processing schemes within this fermionic platform.
