Parallel rearrangement of single atoms with an SLM for quantum simulation

ORAL

Abstract

We present fast parallel rearrangement of single atoms in optical tweezers into arbitrary geometries by updating holograms displayed by an ultra-fast spatial light modulator. Using linear interpolation of the tweezer position and the optical phase between the start and end arrays, we can calculate on-the-fly and display holograms every 2.76(2) ms. To show the versatility of our method, we sort the same atomic sample into multiple geometries with success probabilities exceeding 99% per imaging and rearrangement cycle. We present results on using our rearrangement method for quantum simulation experiments on samples of up to 24 atoms. This work is performed inside the Neutral Atom Kat-1 Collaboration of Quantum Delta NL.
