This paper introduces a state called plus-photon-added two-mode squeezed vacuum state by adding simutaneously plus photons on the both modes of two-mode squeezed vacuum state. By using the linear entropy and the EPR correlation, it is shown that the plus-photon-added two-mode squeezed vacuum state is entangled state and the entanglement degree of this state can tend to the highest degree. Using such state as an entanglement resource to teleport a coherent state, the average fidelity of the quantum teleportation process approaches to unit in the limit of the big amplitude values of the plus-photon-added two-mode squeezed vacuum state.
