Asymmetric bidirectional quantum 1⇔2 qubit teleportation scheme via six-qubit Bell-cluster state

Abstract

Using a six-qubit Bell-cluster state, we proposed an asymmetric bidirectional quantum teleportation scheme. Two participants Anne and Benson are both the sender and receiver. Only applying Bell-state measurement, single- and two-qubit unitary operations as well as classical communication, Anne can transmit an arbitrary two-qubit unknown state to Benson, meanwhile Benson can also send an arbitrary single-qubit unknown state to Anne. Analysis shows that our scheme is feasible with the present experiment technologies.

Cyclic quantum teleportation of two-qubit entangled states by using six-qubit cluster state and six-qubit entangled state

“…In 2013, an original novel protocol for bidirectional controlled quantum teleportation (BCQT) was firstly presented by Zha et al 42 , where Alice and Bob decides together to teleport their quantum states to each other under the supervision of a controller, say Charlie using five-qubit cluster states. Interesting, Yuan and Zhang 43 have suggested an asymmetric BQT scheme feasible with present experimental technologies by using a four-qubit cluster state and a Bell state as a quantum channel. In addition, Wanbin et al 44 have theoretically proposed three BQCT schemes, allowing bidirectional teleportation between two participants with another as the controller, by utilizing seven-qubit maximally entangled states.…”
