Quantum Control of Atom-Photon Entanglement via Structure Light in a Three-Level Medium

In this paper, we look at the quantum manage of entanglement among an atomic system and its spontaneous emission thru structure light. We take into account a three-level medium as a quantum system which interacts with a spatially based vortex light. The quantum system is likewise interacted with incoherent pumping fields which induce extra quantum interference in a medium. We recognize that the quantum entanglement depends at the intensity and orbital angular momentum (OAM) of the implemented light. The impact of incoherent pumping rates and quantum interference resulting from incoherent pumping fields are also mentioned on spatially quantum entanglement in detail. We discover that the OAM number of vortex light has a critical function in our results.
