Controlled Teleportation of an Arbitrary Twoparticle State by Using a Fourqubit Cluster State and Entanglement Swapping
A new scheme for controlled teleportation of an arbitrary twoparticle state is proposed in detail, using a fourparticle 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 Bellbased 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 twoparticle state after he makes the appropriate unitary transformation on his own particles. The success probability of the program is 100%.
