开放量子系统中独立库间的量子干涉

Quantum interference between independent reservoirs in open quantum systems

Ching-Kit Chan, Guin-Dar Lin, Susanne F. Yelin, Mikhail D. Lukin

摘要:

当一个量子系统与多个储层相互作用时,环境效应通常以叠加的方式处理。我们表明,这一假设打破了非马尔可夫环境,有有限的记忆时间。具体来说,我们证明了独立环境之间的量子干涉可以定性地改变物理系统的动力学。我们说明这种效果与两个层次的系统耦合到两个结构化的光子水库,讨论其起源使用非平衡图解技术,并显示一个例子时,这种干扰的应用程序可以导致在一个改进的暗态制备的$λ$系统。

英文摘要:

When a quantum system interacts with multiple reservoirs, the environmental effects are usually treated in an additive manner. We show that this assumption breaks down for non-Markovian environments that have finite memory times. Specifically, we demonstrate that quantum interferences between independent environments can qualitatively modify the dynamics of the physical system. We illustrate this effect with a two level system coupled to two structured photonic reservoirs, discuss its origin using a non-equilibrium diagrammatic technique, and show an example when the application of this interference can result in an improved dark state preparation in a $λ$ system.
