Towards bottom-up assembly of strontium atom arrays

We report on progress towards controlling single strontium atoms in large, defect-free arrays of optical tweezers. Strontium has both bosonic and fermionic species with narrow optical transitions and magic wavelengths, which enable robust cooling, trapping, and coherent manipulation. By using state of the art light shaping technologies and long vacuum-limited lifetimes, we expect to create defect-free arrays of several hundred atoms. We also explore strategies for sideband cooling and non-destructive imaging in optical dipole traps.
