论文摘要
在数值上研究了光子辐射远程电子 - 光子系统中的声子之间的量子纠缠。通过可见/紫外线激光脉冲激发，电子的纠缠立即产生，并且声子的纠缠通过电子形成相互作用遵循，即声子的纠缠生成是一个两步过程。因此，设计入射光脉冲的时间特性很重要，以控制电子和/或声子的纠缠。这些特征是由量子互信息和从海森堡运动方程得出的复合模式揭示的。计算结果还表明，可以通过散射光的时间分辨光谱观察声子纠缠的动力学。
The generation of quantum entanglement between phonons in photoirradiated remote electron-phonon systems is numerically studied. Upon excitation by a visible/ultraviolet laser pulse, the entanglement of electrons is immediately generated and that of phonons follows via electron-phonon interactions, i.e., the entanglement generation of phonons is a two-step process. Therefore, it is important to design the temporal properties of incident optical pulses in order to control the entanglement of electrons and/or phonons. These features are revealed by the quantum mutual information and the composite modes derived from the Heisenberg equation of motion. The calculated results also show that the dynamics of the phonon entanglement can be observed by time-resolved spectroscopy on the scattered light.
