    Abstract

    A new scheme for controlled teleportation of an arbitrary twoparticle state is proposed in detail, using a fourparticle cluster state as quantum channel and EPR state to achieve control. First of all, the sender applies to the controller, and then the controller performs the Bellbased measurement on the two particles of his own. And the controller notifies the sender to achieve entanglement swapping. Then, the sender makes the appropriate unitary transformation and performs a Newman measurements on the four particles of his own. And the results inform the receiver. According to the sender′s measurement results, the receiver can reconstruct the arbitrary twoparticle state after he makes the appropriate unitary transformation on his own particles. The success probability of the program is 100%.
