Transitionless intra-cavity quantum state transfer in optomechanical systems

Abstract

Quantum state transfer between cavities is crucial for quantum information processing and quantum computation in optomechanical systems. Here, we present the first scheme for the transitionless intra-cavity quantum state transfer based on transitionless quantum driving (TQD) algorithm in optomechanical systems. We also present a physically feasible system for the TQD process based on largely detuned optomechanical cavity. With the Gaussian time-dependence coupling strengths, our scheme can achieve the perfect quantum state transfer with no undesired transition and reduce the dependence of accurately controlling evolution time and interval of coupling strengths. Our computational results show that the TQD process can be accomplished with no need of the mechanical oscillator in its ground state and is also robust to the mechanical dissipation.
