标题： Observing dynamical localization on a trapped-ion qudit quantum processor

摘要： 量子处理器的进步为研究物质的奇异状态提供了有前景的新窗口。 一个显著的例子是，在具有大量局部自由度的系统中可能出现非遍历行为。 在这里，我们使用一个捕获离子的高维量子处理器来研究一个无无序的$S=1$ 弗洛凯模型，由于局部自旋相互作用导致动态局域化，该模型变得准稳态。 我们理论描述并实验观察到一种出现的$3T$子谐波响应，证明了在量子比特系统之外见证非遍历动力学的能力。 我们的数值模拟揭示了多体纠缠通过量子费舍尔信息所起的作用，展示了这一量如何成功地反映非平衡情况下遍历和局域化区域之间的转变。 这些结果为研究高维量子系统中的遍历性破坏机制铺平了道路。 显示英文摘要

摘要： The advancements of quantum processors offer a promising new window to study exotic states of matter. One striking example is the possibility of non-ergodic behaviour in systems with a large number of local degrees of freedom. Here we use a trapped-ion qudit quantum processor to study a disorder-free $S=1$ Floquet model, which becomes prethermal by dynamic localization due to local spin interactions. We theoretically describe and experimentally observe an emergent $3T$ subharmonic response, demonstrating the ability to witness non-ergodic dynamics beyond qubit systems. Our numerical simulations reveal the role played by multipartite entanglement through the Quantum Fisher Information, showing how this quantity successfully reflects the transition between ergodic and localized regimes in a non-equilibrium context. These results pave the way for the study of ergodicity-breaking mechanisms in higher-dimensional quantum systems.
