| Abstract: | A scheme of many-party controlled teleportation for multi-qubits entangled W state is proposed. We discuss the way to teleport three-qubits entangled W state from a sender to a receiver via the control of three agents and calculate the fidelity when one of three agents does not cooperate. Then we study the teleportation of many-qubits entangled W state from a sender to a receiver via the control of M agents and calculate the fidelity when X of M agents do not cooperate. |
