Counterdiabatic driving (CD) exploits auxiliary control fields to tailor the nonequilibrium dynamics of a quantum system, making possible the suppression of dissipated work in finite-time thermodynamics and the engineering of optimal thermal machines with no friction. We show that while the mean work done by the auxiliary controls vanishes, CD leads to a broadening of the work distribution. We derive a fundamental inequality that relates nonequilibrium work fluctuations to the operation time and quantifies the thermodynamic cost of CD in both critical and noncritical systems.
反 diabatic 驱动（CD）利用辅助控制场来定制量子系统的非平衡动力学，使得在有限时间热力学中抑制耗散功以及设计无摩擦的最优热机成为可能。我们表明，虽然辅助控制所做的平均功为零，但 CD 会导致功分布变宽。我们推导出一个基本不等式，该不等式将非平衡功涨落与运行时间联系起来，并量化了临界和非临界系统中 CD 的热力学成本。
