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 $\sim 10$ 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.

量子拉比模型的绝热捷径：通过参数放大有效生成巨大的纠缠猫状态

我们提出了一种通过捷径绝热（STA）动力学在超强和深强耦合状态下快速生成Rabi模型的非经典基态的方法。通过将参数放大应用于Jaynes-Cummings模型来模拟时间相关的量子Rabi模型。使用实验可行的参数驱动，此STA协议可以通过以下过程生成大型Schrödinger猫状态：$〜10$相较于绝热方案，速度提高了两倍。这样的快速发展提高了我们协议抗功耗的鲁棒性。我们的方法使人们可以自由设计参数驱动器，从而可以在实验室框架中生成目标状态。在很大程度上失谐的光-质耦合使该协议具有鲁棒性，可以抵抗实验中操作时间的不完美。
