论文摘要
定制光子结构中的量子发射器之间的相干相互作用是未来量子技术的基本构建基础，但在复杂的固态环境中必须挑战，必须考虑在复杂的固态环境中进行腐蚀作用。在这里，我们研究了在现实状态的固态环境中由一维波指导介导的两个量子发射器之间的光学相互作用，重点是在存在下的次级状态的创造，种群和检测。我们表明，随着逐渐增加的增加，次贷的特征迅速消失了强度测量，但在光子相关测量中仍然显着，尤其是当两个发射器分别泵送以使次速度状态有效地填充时。应用的绿色张量方法用于对光子晶体波导进行建模，包括对集成发射极空间位置的依赖。该作品为含有固态发射器的纳米量波导中的子速度状态实现了实验性实现的途径。
Coherent interactions between quantum emitters in tailored photonic structures is a fundamental building block for future quantum technologies, but remains challenging to observe in complex solid-state environments, where the role of decoherence must be considered. Here, we investigate the optical interaction between two quantum emitters mediated by one-dimensional waveguides in a realistic solid-state environment, focusing on the creation, population and detection of a sub-radiant state, in the presence of dephasing. We show that as dephasing increases, the signatures of sub-radiance quickly vanish in intensity measurements yet remain pronounced in photon correlation measurements, particularly when the two emitters are pumped separately so as to populate the sub-radiant state efficiently. The applied Green's tensor approach is used to model a photonic crystal waveguide, including the dependence on the spatial position of the integrated emitter. The work lays out a route to the experimental realization of sub-radiant states in nanophotonic waveguides containing solid-state emitters.
