摘要

中性原子在雷德堡量子计算机中的传输是网格初始排列和动态连接的关键步骤,这一点最近已被成功证明。我们研究了最优控制和量子速度极限在有限温度下光电镊子中中性原子传输中的应用,并分析了激光噪声如何影响传输保真度。开环优化控制显著提高了传输保真度,在 3µm 距离内,最低分析温度为 1µK,传输保真度提高了 89%。此外,我们还模拟了传输保真度在释放和捕获测量中的表现,这些测量可在实验中实现,以估算传输效率并实施闭环优化控制。

Optimal control transport of neutral atoms in optical tweezers at finite temperature
The transport of neutral atoms in Rydberg quantum computers is a crucial step for the initial arrangement of the grid as well as the dynamic connectivity, recently successfully demonstrated. We study the application of optimal control and the quantum speed limit for the transport of neutral atoms in optical tweezers at finite temperatures and analyze how laser noise affects transport fidelity. Open-loop optimal control significantly enhances transport fidelity, achieving an improvement up to 89% for the lowest analyzed temperature of 1µK for a distance of 3µm. Furthermore, we simulate how the transport fidelity behaves in release-and-capture measurements, which are realizable in the experiment to estimate transport efficiency and implement closed-loop optimal control.
