Query: Efficient many-party controlled teleportation of multi-qubit quantum
  information via entanglement   We present a way to teleport multi-qubit quantum information from a sender to
a distant receiver via the control of many agents in a network. We show that
the original state of each qubit can be restored by the receiver as long as all
the agents collaborate. However, even if one agent does not cooperate, the
receiver can not fully recover the original state of each qubit. The method
operates essentially through entangling quantum information during
teleportation, in such a way that the required auxiliary qubit resources, local
operation, and classical communication are considerably reduced for the present
purpose.
