Controlled quantum teleportation via four particle cluster state
A general scheme for controlled teleportation of an arbitrary single-qubit state with four-qubit cluster state is proposed. For an arbitrary single-qubit state,the sender Alice performs the Bell-state measurement on her qubits and the controllers also need take the Bell-state measurement. The receiver David can reconstruct the unknown signal state by performing appropriate unitary operations on his particle if he cooperates with all the controllers.
