摘要:

自旋-玻色子模型是开放量子动力学的典型模型。我们利用一串被困离子模拟自旋-玻色子模型,其中一个自旋与玻色子模式的结构化储层耦合。我们通过调整离子数量、目标离子位置、激光对声子边带的失谐以及激光中的频率分量数,来设计储层的谱密度,并观察它们对初始编码信息坍缩与复苏的影响。我们的工作证明离子阱是模拟具有复杂储层结构的开放量子动力学的强大平台。

英文摘要:

The spin-boson model is a prototypical model for open quantum dynamics. Here we simulate the spin-boson model using a chain of trapped ions where a spin is coupled to a structured reservoir of bosonic modes. We engineer the spectral density of the reservoir by adjusting the ion number, the target ion location, the laser detuning to the phonon sidebands, and the number of frequency components in the laser, and we observe their effects on the collapse and revival of the initially encoded information. Our work demonstrates the ion trap as a powerful platform for simulating open quantum dynamics with complicated reservoir structures.
