Description
Summary:In this study a quantum system of the three-level ladder type interacts with three electromagnetic fields which two of them are coherent and one of them is incoherent. We examine the atom-photon entanglement in the presence of quantum interference from spontaneous emission when two coherent fields become structural lights. We talked about the spatially dependent of the degree of entanglement (DEM) under various parametric conditions of quantum system. We discovered that when the quantum interference reaches a certain level, it is possible to regulate the position dependence of the DEM by altering the orbital angular momentum (OAM) of structure light. Furthermore, our findings demonstrate that one may determine the OAM number of the structure light by counting the regions of the DEM profile.
