In this paper, we investigated the entanglement properties of the generalized superposition of two-mode coherent states SU (1, 1) (STMCSSU) based on the linear entropy criterion. The results show that STMCSSU exhibits a high degree of entanglement and depends on the chosen input parameters. Furthermore, we used the STMCSSU as an entangled resource for the teleportation of a coherent state by using joint measurements of the quadrature amplitude. The results of the fidelity investigation show that the even of two-mode coherent states SU(1,1) is more suitable for quantum teleportation via quadrature-amplitude measurements. In addition, the teleportation fidelity varies appropriately with the input parameters.
