论文摘要
绝热性的快捷方式构成了一种强大的替代方案，可以在模仿绝热动态的同时加快时间进化。它们也与澄清基本问题有关，例如对热力学和量子速度限制的第三个原理的精确量化。在这封信中，我们首次描述了如何在量子场理论中实施与绝热性的快捷方式，以在1 + 1个维度中具有移动壁的腔体内的无质量标量场。该方法基于对利用保形对称性的问题的已知解决方案，并且只要没有动态casimir效应，捷径就会发生。我们获得了用量子场作为工作系统的Otto循环效率的基本限制，这取决于镜像可以达到的最大速度。我们描述了使用超导电路对快捷方式的可能实验实现。
Shortcuts to adiabaticity constitute a powerful alternative that speed up time-evolution while mimicking adiabatic dynamics. They are also relevant to clarify fundamental questions such as a precise quantification of the third principle of thermodynamics and quantum speed limits. In this letter we describe, for the first time, how to implement shortcuts to adiabaticity in quantum field theory, for the particular case of a massless scalar field inside a cavity with a moving wall, in 1 + 1 dimensions. The approach is based on the known solution to the problem that exploits the conformal symmetry, and the shortcuts take place whenever there is no dynamical Casimir effect. We obtain a fundamental limit for the efficiency of an Otto cycle with the quantum field as a working system, that depends on the maximum velocity that the mirror can attain. We describe possible experimental realizations of the shortcuts using superconducting circuits.
