Assembled arrays of Rydberg-interacting atoms
arXiv:2008.04867 · doi:10.1088/1361-6455/ab8b46
Abstract
Assembled arrays of individual atoms with Rydberg-mediated interactions provide a powerful platform for the simulation of many-body spin Hamiltonians as well as the implementation of universal gate-based quantum information processing. We demonstrate the first realization of Rydberg excitations and controlled interactions in microlens-generated multisite trap arrays of reconfigurable geometry. We utilize atom-by-atom assembly for the deterministic preparation of pre-defined 2D structures of rubidium Rydberg atoms with exactly known mutual separations and selectable interaction strength. By adapting the geometry and the addressed Rydberg state, a parameter regime spanning from weak interactions to strong coupling can be accessed. We characterize the simultaneous coherent excitation of non-interacting atom clusters for the state and analyze the experimental parameters and limitations. For configurations optimized for Rydberg blockade utilizing the state , we observe collectively enhanced Rabi oscillations.
