Progress towards Programmable Strontium Atom Arrays

We report on the realization of a programmable atom array created by holographic metasurfaces. We trap bosonic 88-strontium in a variety of geometries using metasurfaces: flat optical devices that are highly integrable and withstand high optical powers. Using a "sorting beam" generated with programmable crossed AODs, we are working towards unity filled arrays in non-periodic patterns. We additionally explore a new magic wavelength of 520 nm for strontium's intercombination line. Leveraging the favorable power handling of metasurface we are exploring the possibility of large-scale high quality arrays with thousands of traps, which is highly desirable for the use of atomic arrays in optical tweezer clocks and for scalable quantum simulation devices. In particular, the setup is geared towards creating highly entangled many-body quantum states that display subradiance.
