论文摘要
作为由半导体中的光和激子形成的准粒子,作为量子总线的激子 - 孔子(EP)作为量子总线有望在室温下开发量子互连设备。但是,材料中EP的显着阻尼通常会导致量子信息的损失。我们提出了一种克服阻尼EP对量子发射器(QES)介导的相关动力学的破坏作用的机制。通过研究单层MOS $ _ {2} $ nanodisk中两个QE和EP之间的近场耦合,我们发现,随着QE的完全耗散,可以有效地避免QE的持续量子相关性,并且可以使QE之间的持续量子相关性产生并稳定在其稳定状态下。这是由于以下事实:随着Qe-mos $ _2 $距离的减少,QE与EP杂交了,以至于它们之间形成了一个或两个绑定的状态。我们的结果提供了一种有用的方法来避免EP阻尼的破坏性影响,并刷新了我们对吸收介质中光 - 物质相互作用的理解。
As a quasiparticle formed by light and excitons in semiconductors, the exciton-polariton (EP) as a quantum bus is promising for the development of quantum interconnect devices at room temperature. However, the significant damping of EPs in the material generally causes a loss of quantum information. We propose a mechanism to overcome the destructive effect of a damping EP on its mediated correlation dynamics of quantum emitters (QEs). Via an investigation of the near-field coupling between two QEs and the EP in a monolayer MoS$_{2}$ nanodisk, we find that, with the complete dissipation of the QEs efficiently avoided, a persistent quantum correlation between the QEs can be generated and stabilized even to their steady state. This is due to the fact that, with upon decreasing the QE-MoS$_2$ distance, the QEs become so hybridized with the EP that one or two bound states are formed between them. Our result supplies a useful way to avoid the destructive impact of EP damping, and it refreshes our understanding of the light-matter interaction in absorbing medium.
