我们在基本但可扩展的单独捕获和控制离子的 2D 架构中演示了 Floquet 工程。失谐捕获势的局部参数调制控制远程离子耦合的强度和运动状态的相关 Peierls 相位。在我们的原理证明中，我们初始化大相干态并调整调制参数来控制声子流的轨迹、方向和干扰。我们的研究结果为未来基于 Floquet 的捕获离子量子模拟器开辟了一条新途径，该模拟器针对相关拓扑现象和动态规范场。
We demonstrate Floquet engineering in a basic yet scalable 2D architecture of individually trapped and controlled ions. Local parametric modulations of detuned trapping potentials steer the strength of long-range interion couplings and the related Peierls phase of the motional state. In our proof of principle, we initialize large coherent states and tune modulation parameters to control trajectories, directions, and interferences of the phonon flow. Our findings open a new pathway for future Floquet-based trapped-ion quantum simulators targeting correlated topological phenomena and dynamical gauge fields.
