Abstract
We propose a novel method for controlling quantum states of light through the manipulation of vacuum fields, enabling the deterministic generation of strongly correlated and entangled photons. This approach provides new capabilities for quantum information processing and long-distance quantum communication. We consider a Λ-type three-level atom embedded in a QED cavity, where one atomic transition is driven by a classical field while the other interacts with a cavity-modified vacuum field with chirped frequency modulation. The coherent interplay between the classical and vacuum fields allows the generation of quantum optical states with tunable correlations and spectral properties. These results suggest promising applications in quantum sensing, single-photon spectroscopy, and quantum teleportation.
