文摘In this letter a cascade quantum teleportation scheme is proposed.The proposed scheme needs less local quantum operations than those of quantum multi-teleportation.A quantum teleportation scheme based on entanglement swapping is presented and compared with the cascade quantum teleportation scheme.Those two schemes can effectively teleport quantum information and extend the distance of quantum communication.
