Abstract
In this paper, we propose a simple and useful scheme to realize the teleportation of a two-qubit entangled state with the help of four-qubit cluster state in trapped ions which involves the interaction of two ions. Our scheme uses a cluster state as the quantum channel, where we do not need any Bell-state measurement. Thus it is insensitive to the thermal motion, which is of importance in view of experiment. Meanwhile, the successful probability can both reach 1.0.
