We present the progress towards the construction of a dipolar quantum gas microscope using dysprosium atoms. This new apparatus combines the single-site resolution of a quantum gas microscope with the long-range and anisotropic interactions found in dipolar quantum gases. We will use fermionic and bosonic isotopes of dysprosium trapped in an ultraviolet optical lattice with a lattice spacing of 180 nm. Combined with the long-range dipole interaction, the short lattice spacing will significantly enhance nearest neighbor coupling to be on the order of 200 Hz (10 nK). We will combine this lattice setup with a single-particle, spin-, and energy resolved super-resolution imaging technique. This will allow us to experimentally study strongly correlated dipolar Bose- and Fermi-Hubbard physics, where even next-nearest-neighbor interactions could become visible. The strong and tunable dipolar interactions open up the possibility to explore a wide range of problems ranging from quantum magnetism and lattice spin models to topological matter.
