FermiQP is a demonstrator for a fermionic quantum processor utilizing ultracold fermions in optical lattices. Operating in analog mode, the system facilitates precision studies of the two-dimensional Fermi-Hubbard model. In its digital mode, it aims to implement a universal gate set on the spin degree of freedom, enabling advanced state engineering and local basis transformations. We present a single-atom addressing scheme for coherently manipulating the internal states of individual Lithium-6 atoms in an optical lattice. The scheme employs differential light shifts near a UV transition at 323 nm, maximizing atomic coherence while minimizing cross-talk to neighboring lattice sites. We report on the characterization of our high numerical aperture UV microscope objective and the current status of the implementation of our single-site addressing setup, which incorporates two polarization independent AODs.
