Lamb-Dicke Dynamics of Rydberg Atoms in Optical Tweezers — •Aslam Parvej1,2, Lia Kley1,2, and Ludwig Mathey1,2 — 1Zentrum für Optische Quantentechnologien, Universität Hamburg, 22761 Hamburg, Germany — 2Institut für Quantenphysik, Universität Hamburg, 22761 Hamburg, Germany
Neutral Rydberg atoms trapped in optical tweezer arrays provide a platform for quantum simulators and computation. In this study, we investigate the dynamics of the Lamb-Dicke-coupled internal states of the atoms, which form the logical qubits, in conjunction with the motion of the optical tweezers across different parameter regimes. In this setup, the logical qubit is coupled to a laser with a Rabi frequency, while each atom is also harmonically trapped with a trap frequency. The impact of coherent motion of the optical tweezers on collective non-equilibrium dynamics of the Rydberg atom is explored for varying Lamb-Dicke parameters and resonant Rabi frequencies.
