    "abstract": "We present a way to teleport multi-qubit quantum information from a sender to\na distant receiver via the control of many agents in a network. We show that\nthe original state of each qubit can be restored by the receiver as long as all\nthe agents collaborate. However, even if one agent does not cooperate, the\nreceiver can not fully recover the original state of each qubit. The method\noperates essentially through entangling quantum information during\nteleportation, in such a way that the required auxiliary qubit resources, local\noperation, and classical communication are considerably reduced for the present\npurpose.",
