Neutral-atom arrays in optical tweezers have been demonstrated to be a reliable platform for quantum simulation and computing. In this context, the high complexity of lanthanides (e.g. Erbium[1]) translates into excellent prospects for their employment on quantum operations due to magical conditions, narrow-linewidth transitions and trappable Rydberg states, besides providing an 8-dimensional hyperfine manifold for the ground-state of the fermionic isotope Er167.
In this work, we present the latest developments in our tweezer-array platform with the Lanthanide Er166. We found a magical condition for the MOT light, which enhances atom loading on the tweezer, and we are now approaching the single-atom regime. We have already addressed roughly 550 Rydberg states [2], including an excitation to an ng-state enabled by the submerged, 4f-shell of Erbium. We will soon start studying novel Rydberg excitation schemes addressing large-angular-momentum states and the high-dimensional hyperfine manifold of the fermionic isotope, both of which will be useful for quantum simulation purposes.
