| Abstract: | A scheme for teleporting an arbitrary tripartite entangled state is proposed when three bipartite entangled states (|η〉) with continuous variables are used as quantum channels. Quantum teleportation can be carried out successfully if the receiver adopts an appropriate unitary transformation. The calculation is greatly simplified by virtue of the Schmidt decompositions of both tripartite entangled state |p t ,χ 2,χ 3〉 and |η〉. Any tripartite state which can be expanded in terms of |p t ,χ 2,χ 3〉 may be teleported in this way due to the completeness of |p t ,χ 2,χ 3〉. |
