Rapid Production of Uniformly Filled Arrays of Neutral Atoms

We demonstrate rapid loading of a small array of optical tweezers with a single Rb-87 atom per site. We find that loading efficiencies of up to 90% per tweezer are achievable in less than 170 ms for traps separated by more than 1.7 mu m. Interestingly, we find the load efficiency is affected by nearby traps and present the efficiency as a function of the spacing between two optical tweezers. This enhanced loading, combined with subsequent rearranging of filled sites, will enable the study of quantum many-body systems via quantum gas assembly.
