    Abstract

    A new application of the fivequbit cluster state is investigated for economic and simple controlled teleportation of an arbitrary twoqubit state. In this scheme, a fivequbit cluster state is shared by a sender (Alice), a controller (Charlie) and a receiver (Bob), and the sender only needs to perform Bellstate measurements and the controller performs a singlequbit projective measurement. The receiver can reconstruct the arbitrary twoqubit 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 multiparticle joint measurement that makes this scheme simpler.
