摘要
The development of quantum technologies present important challenges such asthe 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. Inthis paper we present a shortcut to adiabaticity for the control of anoptomechanical cavity with two moving mirrors. Given reference trajectories forthe mirrors, we find analytical expressions that give us effective trajectorieswhich implement a STA for the quantum field inside the cavity. We then solvethese equations numerically for different reference protocols, such asexpansions, contractions and rigid motions; thus confirming the successfulimplementation of the STA and finding some general features of these effectivetrajectories.
