%X A scheme of M-party controlled teleportation for N-qubits entangled W state via (N-1) EPR pairs and one (M+2)-qubits GHZ state is proposed. We achieve the teleportation in such a way that M agents execute the Hadamard transformation, perform the measurement on their qubits and tell the outcome of measurement to receiver. Then we discuss that the receiver can not fully recover the state of the sender if one agent does not cooperate.
