Economic and Simple Controlled Teleportation of an Arbitrary Twoqubit State Using Fivequbit Cluster State
A new application of the fivequbit cluster state is investigated for economic and simple controlled teleportation of an arbitrary twoqubit state. In this scheme, a fivequbit cluster state is shared by a sender (Alice), a controller (Charlie) and a receiver (Bob), and the sender only needs to perform Bellstate measurements and the controller performs a singlequbit projective measurement. The receiver can reconstruct the arbitrary twoqubit state by performing some appropriate unitary transformations on his qubits after he knows the measured results of both the sender and the controller. This controlled teleportation scheme is deterministic, and the probability of successful controlled teleportation is 100%. In comparison with the controlled teleportation scheme using the same quantum channel, the proposed scheme do not need to make multiparticle joint measurement that makes this scheme simpler.
