Abstract
We put forward an efficient quantum controlled teleportation scheme, in which arbitrary two-qubit state is transmitted from the sender to the remote receiver via two entangled states under the control of the supervisor. In this paper, we use the combination of one two-qubit entangled state and one three-qubit entangled state as quantum channel for achieving the transmission of unknown quantum states. We present the concrete implementation processes of this scheme. Furthermore, we calculate the successful probability and the amount of classical information of our protocol.
Highlights
Quantum teleportation theoretical scheme was first proposed by Bennett et al in 1993 [1], where one unknown quantum state could be transmitted via Einstein-Podolsky-Rosen (EPR) pair with the help of classical information
In this paper, based on quantum controlled teleportation protocol we propose a method for transmitting arbitrary two-qubit state via one two-qubit entangled state and one three-qubit entangled state as quantum channel, where the Greenberger-Horne-Zeilinger (GHZ) state and Bell state are utilized
For achieving the transmission of two-qubit state, we use the combination of one GHZ state and one Bell state as quantum channel
Summary
Quantum teleportation theoretical scheme was first proposed by Bennett et al in 1993 [1], where one unknown quantum state could be transmitted via Einstein-Podolsky-Rosen (EPR) pair with the help of classical information. Due to its high confidentiality and reliability, it is superior to conventional electrical communication In the teleportation, both of the sender and the receiver do not know the transmitted quantum state in advance. In many researches on quantum controlled teleportation, it has been realized that one-qubit unknown state can be transmitted by using of the three-particle entangled states as quantum channel. In this paper, based on quantum controlled teleportation protocol we propose a method for transmitting arbitrary two-qubit state via one two-qubit entangled state and one three-qubit entangled state as quantum channel, where the Greenberger-Horne-Zeilinger (GHZ) state and Bell state are utilized. We calculate the successful probability and the amount of classical information of our protocol
