我们提出了一种利用冷原子和离子的里德伯态进行电子-声子相互作用量子模拟的方法。我们展示了如何将冷原子和离子系统映射到Su-Schrieffer-Heeger类型的电子-声子系统。我们讨论了如何调整模拟哈密顿量的属性，以及如何从模拟器中读取物理相关属性。特别是，使用涂点势提供了高水平的可调性，使电子-声子哈密顿量的所有物理相关区域都可以访问。
We propose an approach for quantum simulation of electron-phonon interactions using Rydberg states of cold atoms and ions. We show how systems of cold atoms and ions can be mapped onto electron-phonon systems of the Su-Schrieffer-Heeger type. We discuss how properties of the simulated Hamiltonian can be tuned and how to read physically relevant properties from the simulator. In particular, use of painted spot potentials offers a high level of tunability, enabling all physically relevant regimes of the electron-phonon Hamiltonian to be accessed.
