Progress Towards Programmable Strontium Atom Arrays

POSTER

Abstract

We report on progress towards realizing a platform for programmable arrays of strontium atoms. Atom arrays have rapidly become a paradigm for exploring quantum systems, with the rich internal structure of alkaline earth atoms enabling new research avenues. On route to this goal, we demonstrate a novel dispenser-based atom source that is compact and adaptable for other experiments. Using optical tweezers generated by holographic metasurfaces, we explore trapping of atoms in a diverse set of geometries relevant to condensed matter systems, such as quasicrystals and twisted bilayer graphene. The optical tweezers operate at a magic wavelength for strontium. The setup is geared towards creating highly entangled many-body quantum states that display subradiance. In addition, our platform lends itself for applications in quantum simulation and quantum computation.
