In this paper, we investigate and compare the entanglement properties between the generalized photon-added pair coherent state (GPAPCS) and the superposition photon-added pair coherent state (SPAPCS) by using the Von Neumann entropy criterion. We then use these two states as entanglement resources to quantum teleportation processes, thereby evaluating and comparing the average fidelity of these processes. The results show that both GPAPCS and SPAPCS exhibit high entanglement properties and have great potential for application in quantum teleportation. Furthermore, in some cases, SPAPCS demonstrates better entanglement properties, and the average fidelity of the quantum teleportation using this state is also higher than that of GPAPCS.
