Abstract
We propose a scheme that exploits the effect of normal-mode splitting in a three-mode optomechanical system (OMS) to manipulate phonons in a single-excitation level. The three normal modes of the OMS are formed by coupling two mechanical modes to a cavity mode, which is driven by a strong red-detuned pump field via radiation pressure. It is shown that the Landau–Zener dynamics of the three-normal-mode configuration is versatile for quantum information engineering. Explicitly, we show that it is feasible to transfer a single phonon between two mechanical modes with distinct frequencies, and an entangled state among the three modes can be prepared. The effect of damping is analyzed by numerical simulation, which confirms the validity of our proposal.
