论文摘要
绝热性（STA）的快捷方式与对量子系统的动力学的快速和牢固操纵有关，该动力学再现了绝热过程的效果。最近提出的一种方法可以通过简单地重新缩放量子进化运算符的时间变量[B. B. L. Bernardo，物理。 Rev. Research 2，013133（2020）]。这种时间响应的方法不需要有关哈密顿量的特征值和特征态的知识，在许多情况下，没有其他耦合领域。在这里，我们使用这种方法来研究加速两级量子系统的种群反转的问题。控制参数中的动力学与系统误差的保真度被证明与其他STA方案相当。从量子热力学的角度来看，我们还证明了沿快捷方式驱动系统所需的工作分布的主要特性相对于参考（慢）协议没有改变。
A shortcut to adiabaticity (STA) is concerned with the fast and robust manipulation of the dynamics of a quantum system that reproduces the effect of an adiabatic process. A recently proposed method enables the generation of shortcuts from a prescribed slow dynamics by simply rescaling the time variable of the quantum evolution operator [B. L. Bernardo, Phys. Rev. Research 2, 013133 (2020)]. This time-rescaling method does not demand knowledge about the eigenvalues and eigenstates of the Hamiltonian, and in many cases no additional coupling fields. Here, we use this approach to study the problem of speeding up the population inversion of a two-level quantum system. The fidelity of the dynamics versus systematic errors in the control parameters are shown to be comparable with other STA schemes. From a quantum thermodynamic viewpoint, we also demonstrate that the main properties of the distribution of work required to drive the system along the shortcuts are unchanged with respect to the reference (slow) protocol.
