Parallel Assembly of Arbitrary Defect-Free Atom Arrays with a Multitweezer Algorithm

Defect-free atom arrays are a precursor for quantum information processing and simulation with neutral atoms. Yet, large-scale defect-free can be challenging to realize, due the losses encountered when rearranging stochastically loaded atoms achieve desired target array. Here, we demonstrate parallel rearrangement algorithm that uses multiple mobile tweezers independently sort compress in way naturally avoids collisions. With high degree of parallelism, our offers reduced move complexity compared both single-tweezer algorithms existing multitweezer algorithms. We further determine optimal parallelism balance between an algorithmic speedup inhomogeneity effects. The probability 225-atom array is demonstrated as 33(1)% room-temperature setup after cycles rearrangement. presented here implemented any geometry underlying periodic structure.Received 13 September 2022Revised 15 December 2022Accepted 19 January 2023DOI:https://doi.org/10.1103/PhysRevApplied.19.034048Published by American Physical Society under terms Creative Commons Attribution 4.0 International license.
