摘　　要：讨论了三粒子纠缠W态的三人控制的隐形传输和控制方中有一个人、两个人和三个人不合作时接收方获得发送方的量子态的保真度,接着研究了多粒子纠缠W态的多控制隐形传输的方案,并且讨论了当有X个控制方不合作时接收方获得发送方的量子态的保真度。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.
