Gauge theories play a fundamental role for our understanding of nature, ranging from high-energy to condensed matter physics. Their formulation on a regularized periodic lattice geometry, so-called lattice gauge theories (LGTs), has proven invaluable for theoretical studies. However, as numerical simulations are limited in their capability to simulate, e.g., the real-time dynamics, there have been sustained efforts to develop quantum simulators for LGTs. We report on our recent progress on constructing a novel experimental platform for ytterbium atoms, which employs optical lattices and optical tweezers to engineer and probe LGTs. In contrast to other experimental realizations, this approach allows for a robust and scalable implementation of local gauge invariance. A central component enabling this favorable property are optical tweezer potentials operated at the tune-out wavelengths for the ground and clock state of ytterbium. Notably, optical potentials generated from light at these wavelengths could also find applications for digital quantum computation. We present our efforts towards precisely determining these wavelengths experimentally.
