论文摘要
固态光子系统系统中的声子相互作用会引起固有的量子反应性，并且通常呈现出新兴量子技术的限制因素。由于最近在纳米光子学方面的发展，可以制造具有非常强大的光结合速率的激子腔内结构。我们表明，在这样的结构中，出现了一个新的制度，由于主导声子过程的脱钩，将完全抑制了折叠。使用数值精确的张量网络方法，我们在这种非扰动的非马克维亚动力学方面执行计算。在这里，我们确定了达到近乎不可分性的策略，还发现了高Q策略中激子腔极性子的有趣的声子装饰，当轻度互动足够强时，导致多个声子侧带。
Phonon interactions in solid-state photonics systems cause intrinsic quantum decoherence and often present the limiting factor in emerging quantum technology. Due to recent developments in nanophotonics, exciton-cavity structures with very strong light-matter coupling rates can be fabricated. We show that in such structures, a new regime emerges, where the decoherence is completely suppressed due to decoupling of the dominant phonon process. Using a numerically exact tensor network approach, we perform calculations in this non-perturbative, non-Markovian dynamical regime. Here, we identify a strategy for reaching near-unity photon indistinguishability and also discover an interesting phonon-dressing of the exciton-cavity polaritons in the high-Q regime, leading to multiple phonon sidebands when the light-matter interaction is sufficiently strong.
