In this contribution, we study a single Cooper pair box interacts with a single cavity mode. We show the roles played by the detuning parameters and charged capacities on the degree of entanglement. For large values of the detuning parameter the survival entanglement increases on the expanse of the degree of entanglement. We generate a maximum entangled state and use it to perform the original teleportation protocol. The fidelity of the teleportated state is increased with decreasing the detuning parameter and the number of photon inside the cavity.
