论文摘要
量子技术的开发提出了重要的挑战,例如需要快速,精确的协议来实施量子操作。绝热性(STA)的快捷方式是实现这些目标的有力工具,因为它们使我们能够在有限的时间内执行绝热的演变。在本文中,我们提出了对控制具有两个移动镜的光力学腔的绝热性快捷方式。给定镜子的参考轨迹,我们发现分析表达式为我们提供有效的轨迹,这些轨迹为腔体内的量子场实施了sta。然后,我们将这些方程式求解用于不同的参考方案,例如扩展,收缩和刚性动作;因此,确认了STA的成功实施,并找到了这些有效轨迹的一些一般特征。
The development of quantum technologies present important challenges such as the need for fast and precise protocols for implementing quantum operations. Shortcuts to adiabaticity (STA) are a powerful tool for achieving these goals, as they enable us to perform an exactly adiabatic evolution in finite time. In this paper we present a shortcut to adiabaticity for the control of an optomechanical cavity with two moving mirrors. Given reference trajectories for the mirrors, we find analytical expressions that give us effective trajectories which implement a STA for the quantum field inside the cavity. We then solve these equations numerically for different reference protocols, such as expansions, contractions and rigid motions; thus confirming the successful implementation of the STA and finding some general features of these effective trajectories.
