Efficient many-party controlled teleportation of multiqubit quantum information via entanglement

Chui‐Ping Yang, Shih‐I Chu, Siyuan Han

We present a way to teleport multiqubit 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 cannot 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.We present a way to teleport multiqubit quantum information from a sender to a distant receiver via the control of many agents in a network.

Controlled Teleportation of Multi-qutrit Quantum Information by Swapping Entanglement

Jie Yang, Jun Liu

We present a scheme for teleporting multi-qutrit quantum information from a sender to a receiver via the control of many agents in a network. Agents's control parameters are obtained via quantum entanglement swapping. In our scheme, Zhang and Man's QSS protocol [Phys. Rev. A 72 (2005) 022303] based on Bell-state entanglement swapping is generalized to a qutrit case. Our scheme owns the advantage of having higher code capacity and better security than the work [Commun. Theor. Phys. 44 (2005) 847] on controlled teleportation for multi-qubit.We present a scheme for teleporting multi-qutrit quantum information from a sender to a receiver via the control of many agents in a network.
