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.
