    Abstract

    Based on the strong persistency of entanglement of cluster state, two quantum sharing schemes were presented to realize the controlled teleportation of an arbitrarily one-particle using a four-particle cluster state as the quantum channel. In the first scheme, the sender Alice, controller Charlie and receiver Bob share a four-particle cluster entangled state. Firstly Alice performs a three-particle joint Von-Neumann measurement on her qubits. Then Charlie performs a quantum measurement on his qubit with Z basis. Finally Bob can reconstruct the shared single particle by doing unitary transformation according to the measured results from Charlie and Bob. In the second scheme, three parties also shared a four-particle cluster state and an auxiliary particle, Alice and Charlie only need Bell state measurements and Bob can get the transmitted state by performing a swap bit flip operation and one unitary transformation. Compared with the existing schemes, the success probability of these both schemes are 100% and the proposed schemes only need 4-particle cluster state as the quantum channel. Furthermore, the proposed schemes can be implemented under the current laboratory techniques.
