Abstract
We present a method to teleport multi-qubit quantuminformation in an easy way from a sender to a receiver via thecontrol of many agents in a network. Only when all the agentscollaborate with the quantum information receiver can the unknownstates in the sender's qubits be fully reconstructed in thereceiver's qubits. In our method, agents's control parameters areobtained via quantum entanglement swapping. As the realization ofthe many-agent controlled teleportation is concerned, compared tothe recent method [C.P. Yang, et al., Phys. Rev. A 70(2004) 022329], our presentmethod considerably reduces the preparation difficulty of initialstates and the identification difficulty of entangled states,moreover, it does not need local Hadamard operations and it ismore feasible in technology.
