摘要：

An asymmetric bidirectional quantum teleportation scheme was proposed by utilizing a seven-qubit entangled state as quantum channel. The scheme can perfectly achieve the transmission of a three-qubit target entangled state from one legitimate user Alexis to the other legitimate user Billy. Simultaneously, another two-qubit target entangled state can be reversibly conveyed from Billy to Alexis. The implementation of the scheme requires only Bell-state measurements and some simple necessary quantum operations. The impact of phase-damping noise on our scheme is investigated by calculating and discussing its fidelity. Compared with some analogous schemes, the proposed scheme has many significant advantages, such as less quantum and classical resources consumed, higher intrinsic efficiency, lower execution difficulty. Furthermore, it has strong compatibility and experimental feasibility.
