Quantum teleportation via entangled states generated by the Jaynes–Cummings model

In this contribution, quantum channels induced from an atom-field interaction (JCM), are used to teleport one and two qubit states. The initial state of the filed is taken to be in a coherent state while the atom starts from its excited state. The field parameters could be used as control parameters. It is shown that the fidelity of the teleported state depends on the fidelity of the input state, the degree of entanglement and the mixedness of the quantum channels. Finally, we find that a higher entangled channel is needed for a higher entangled state to be teleported.
