Rapid out-of-plane motion of optical tweezers for atom array reconfiguration

ORAL

Abstract

Acoustic-Optic deflectors (AOD) are commonly used for long-range transport and sorting of neutral atom arrays, an emerging platform for quantum computing. I'm going to talk about the out-of-plane and astigmatic nature of rapidly moving tweezers, due to finite sound velocity in the AOD crystal. This phenomenon fundamentally limits the speed of atom transport, which is crucial for combating decoherence on atomic qubits. Then I will show three different novel approaches to mitigate this problem, in order to achieve rapid long-range qubit transportation and reconfiguration. The last approach, will be ultimately inspirational to atom array sorting in 3D.
