论文摘要
我们系统地研究同时调节输入激光强度和量子点（QD）谐振的频率对嵌入QD嵌入的光学半导体谐振器中的平均场动力学，波动能量转移和纠缠的量子频率。我们表明，可以对调制和混合系统进行设计以实现所需的平均场值，控制波动的能量转移以及各种自由度之间的纠缠。仅通过调节QD频率可以实现非常高的纠缠程度。两种调制之间的相互作用导致纠缠，该纠缠仅通过调节QD或泵激光强度而产生的纠缠。当我们打开调制时，从低静止的动力纠缠从低静止的动力纠缠发生。这项研究为最佳控制策略开辟了新的可能性，可用于数据信号传输和量子通信平台中的存储。
We systematically study the influence of simultaneously modulating the input laser intensity and quantum dot (QD) resonance frequecy on the mean-field dynamics, fluctuation energy transfer and entanglement in a optomechanical semi-conductor resonator embedded with a QD. We show that the modulation and the hybrid system can be engineered to attain the desired mean-field values, control the fluctuation energy transfer and the entanglement between the various degrees of freedom. A remarkably high degree of entanglement can be achieved by modulating only the QD frequency. The interplay between the two modulations leads to an entanglement which lies between that generated solely by modulating either the QD or the pump laser intensity. A transition from low stationary to large dynamical entanglement occurs as we switch on the modulation. This study opens up new possibilities for optimal control strategies and can be used for data signal transfer and storage in quantum communication platforms.
