论文摘要
我们提出了一种通过快捷方式到可绝经（STA）动力学的超局势和深度耦合方案中RABI模型快速生成的非经典基态的方法。通过将参数放大应用于Jaynes-Cummings模型来模拟时间依赖性的量子Rabi模型。使用实验可行的参数驱动器，该Sta协议可以通过与绝热协议快10倍的过程来生成大尺寸的SchrödingerCat状态。如此快速的演化增加了我们的方案抗耗散的鲁棒性。我们的方法使一个人可以自由设计参数驱动器，以便可以在实验室框架中生成目标状态。在实验中，在很大程度上失调的光 - 物体耦合使协议可与操作时间的缺陷进行鲁棒化。
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.
