Fast and robust quantum control for multimode interactions by using shortcuts to adiabaticity
Abstract
Adiabatic quantum control is a very important approach for quantum physics and quantum information processing. It holds the advantage with robustness to experimental imperfections but accumulates more decoherence due to the long evolution time. Here, we propose a universal protocol for fast and robust quantum control in multimode interactions of a quantum system by using shortcuts to adiabaticity. The results show this protocol can speed up the evolution of a multimode quantum system effectively, and it can also keep the robustness very good while adiabatic quantum control processes cannot. We apply this protocol for the quantum state transfer in quantum information processing in the photon-phonon interactions in an optomechanical system, showing a perfect result. These good features make this protocol have the capability of improving effectively the feasibility of the practical applications of multimode interactions in quantum information processing in experiment.

Comments
7 pages, 6 figures. The text overlaps partially with arXiv: 1610.09938. A general way is given for the fast and robust quantum control on multimode interactions by using shortcuts to adiabaticity, not just the transitionless intra-cavity quantum state transfer in optomechanical systems in arXiv: 1610.09938 (an application of this way). That is, the goal and the method are changed largely
