摘要:

提出了一种利用捷径绝热(STA)动力学方法快速产生Rabi模型在超强和深强耦合区的非经典基态的方法。通过对Jaynes-Cummings模型施加参量放大,模拟了含时量子Rabi模型。使用实验上可行的参数驱动,STA协议可以通过比绝热协议快10倍的过程生成大尺寸薛定谔猫态。这种快速的演变增加了我们的协议对耗散的鲁棒性。我们的方法使一个自由设计的参数驱动器,使目标状态可以在实验室框架中生成。一个很大程度上失谐的光-物质耦合,使协议强大的对实验中的操作时间的缺陷。

英文摘要:

We propose a method for the fast generation of nonclassical ground states of the Rabi model in the ultrastrong and deep-strong coupling regimes via the shortcuts-to-adiabatic (STA) dynamics. The time-dependent quantum Rabi model is simulated by applying parametric amplification to the Jaynes-Cummings model. Using experimentally feasible parametric drive, this STA protocol can generate large-size Schrödinger cat states, through a process that is 10 times faster compared to adiabatic protocols. Such fast evolution increases the robustness of our protocol against dissipation. Our method enables one to freely design the parametric drive, so that the target state can be generated in the lab frame. A largely detuned light-matter coupling makes the protocol robust against imperfections of the operation times in experiments.
