论文摘要

我们研究了非马克维亚增强效应在一条耦合到1D波导的线性链中的集体链中自发发射中的非马多维亚增强效应。我们发现,对于量子位的临界分离,该系统表现出超级超级(SSR)的行为,导致集体衰减比通常的dicke超赞。在这里,时间延迟的相干量子反馈效果在通常的dicke超级效果的基础上发挥了作用。我们找到了SSR衰减速率的线性缩放率,量度增加了$ n $,因此$γ_{\ rm ssr} \ sim 2.277nγ_0$,其中$γ_0$是单个发射极衰减速率,与一维波相反,与$γ_ $ qug _ _ \ rmmmmmmmmm dicke}相反,超级奉献。 SSR衰减速率可以用量子分离距离调整,因此可以应用量子技术。

We study non-Markovian enhancement effects in the spontaneous emission of a collective excitation in a linear chain of up to 100 qubits coupled to a 1D waveguide. We find that for a critical separation of qubits, the system exhibits super-superradiant (SSR) behavior leading to collective decay stronger than the usual Dicke superradiance. Here, time-delayed coherent quantum feedback effects are at play on top of the usual Dicke superradiance effects. We find a linear scaling for the SSR decay rate with increasing qubit number $N$ such that $Γ_{\rm SSR} \sim 2.277 N γ_0$, where $γ_0$ is the single emitter decay rate to a one-dimensional waveguide, as opposed to $Γ_{\rm Dicke}\sim N γ_0$ for Dicke superradiance. The SSR decay rate can be tuned with qubit separation distance and may therefore have application for quantum technologies.
