Phase-Controlled Atom-Photon Entanglement in a Three-Level lambda-Type
Closed-Loop Atomic System
   [PDF]

Ali Mortezapour, Zeinab Kordi, Mohammad Mahmoudi
The atom-photon entanglement is studied in a three-level lambda-type closed-loop atomic system in multi-photon resonance condition and beyond it. It is shown that the von Neumann entropy in such a system is phase dependent, and it can be controlled by either intensity or relative phase of applied fields. It is demonstrated that for the special case of Rabi frequency of applied fields, the system is disentangled.
