We demonstrate deterministic preparation of arbitrary two-component product states of fermionic 6Li atoms in an 8×8 optical tweezer array, achieving motional ground-state fidelities above 98.5 %. Leveraging the large differential magnetic moments for spin-resolution, with parallelized site- and number-resolved control, our approach addresses key challenges for low-entropy quantum state engineering. Combined with high-fidelity spin-, site-, and density-resolved readout within a single 20 μs exposure, and 3 s experimental cycles, these advances establish a fast, scalable, and programmable architecture for fermionic quantum simulation.
