The Tavis–Cummings system, wherein emitters collectively interact with the same optical mode, has been a long-standing model to study collective photon emission phenomena such as superradiance. However, disorder in the resonant frequencies of the quantum emitters can perturb these effects. In this paper, we study the impact of dynamic modulation on the interplay between superradiance and spectral disorder. Through numerical simulations and analytical calculations, we provide evidence that the effective cooperativity of the superradiant mode can be multiplicatively enhanced with a quantum control protocol modulating the resonant frequency of the optical mode. Our results are relevant to experimental demonstration of superradiance in solid-state quantum optical systems, wherein the spectral disorder is a signficant technological impediment toward achieving photon-mediated emitter–emitter couplings.

通过动态调制增强光谱不均匀腔 QED 系统的超辐射度

Tavis-Cummings 系统，其中发射器集体与相同的光学模式相互作用，一直是研究集体光子发射现象（如超辐射）的长期模型。然而，量子发射器共振频率的无序会干扰这些效应。在本文中，我们研究了动态调制对超辐射与光谱无序相互作用的影响。通过数值模拟和分析计算，我们提供的证据表明，通过调制光学模式的谐振频率的量子控制协议可以成倍地增强超辐射模式的有效协同性。我们的结果与固态量子光学系统中超辐射的实验证明有关，
