The Scheme of Entanglement Swapping in two-photon Jaynes-Cummings model
Liu Hong · Journal of Gansu Lianhe University · 2008
Based on the interaction of atoms and two-photon in cavity QED,the author proposes an entanglement swapping scheme without joint measurement using a two-photon Jaynes-Cummings model.By means of entanglement swapping,we get a nonmaximally entangled pair between an atom and a cavity mode which previously have not any interaction with each other.Through entanglement concentration,we can obtain a maximally entangled state.It can be used in quantum information processing.
