“…[37], since the introduction of a controller can effectively prevent a dishonest sender from not sending messages. What's more, in comparison with the bidirectional hybrid communication protocols, [18][19][20][21][22][23] quantum information is just transmitted between two parties, but our protocol can transmit information among multiple participants. Compared to other cyclic communication protocols, [24][25][26][27][28][29][30][31] our protocol can transmit information in two directions, in which the participants can send quantum states to each other.…”

“…In addition, a hybrid protocol [22] for transferring single-qubit stats by realizing QT and RSP under the amplitude-damping noisy environment was also discussed. Lately, introducing the idea of bidirectional hybrid communication into quantum networks, Zhang and Jiang put forward a butterfly network coding protocol [23] by utilizing a five-qubit Brown state. The hybrid communication scheme mentioned above can make better use of quantum channels, but only can realize information transmission between two parties.…”

Hybrid quantum communication with the combination of quantum teleportation and remote preparation is hopeful for promoting the development of quantum networks and enriching the diversity of quantum network communication. To improve the communication efficiency and enhance the scalability of the quantum networks, a meaningful protocol for controlled cyclic and bidirectional hybrid quantum communication of arbitrary two‐qubit states is proposed, which allows quantum information to be transmitted simultaneously in both directions among multiple participants. With the permission of one controller, each observer can simultaneously transmit arbitrary known two‐qubit states and unknown ones to their adjacent observers, by implementing remote preparation and quantum teleportation in the clockwise and counterclockwise directions. Furthermore, the participants just carry out some quantum measurements and recovery operations to achieve the communication target, and the desired states can be attained with a unit success probability, thus the protocol is deterministic. Finally, some comparisons are also made with other similar protocols, which shows that the protocol is better in qubit efficiency and communication capacity.
