Coherent control of quantum and entanglement dynamics via periodic modulations in optomechanical semiconductor resonator coupled to quantum-dot excitons

We systematically study the influence of simultaneously modulating the input laser intensity and quantum-dot (QD) resonance frequency on the mean-field dynamics, fluctuation energy transfer and entanglement in a optomechanical semiconductor resonator embedded with a QD. We show that the modulation and the hybrid system can be engineered to attain the desired mean-field values and control the fluctuation energy transfer and the entanglement among the various degrees of freedom. A remarkably high degree of entanglement can be generated by modulating only the QD frequency. The interplay between the two modulations leads to a decrease in the entanglement. Switching on the modulation leads to a transition from low stationary to large dynamical entanglement. This investigation provides novel strategies to coherently control data signal transfer and storage in quantum information processing networks.
