We propose the implementation of the Holstein model by means of digital methods in a linear chain of trapped ions. We show how the simulation fidelity scales with the generation of phononic excitations. We propose a decomposition and a stepwise trapped-ion implementation of the Holstein Hamiltonian. Via numerical simulations, we study how the protocol is affected by realistic gates. Finally, we show how measurements of the size of the simulated polaron can be performed.
我们提出通过数字方法在被困离子线性链中实现 Holstein 模型。我们展示了模拟保真度如何随声子激发的产生而变化。我们提出了 Holstein 哈密顿量的分解和分步离子阱实现。通过数值模拟，我们研究了协议如何受到实际门的影响。最后，我们展示了如何进行模拟极化子大小的测量。
