“…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. All in all, our scheme enables simultaneous bidirectional transmission of quantum states among multiple participants, it can greatly reduce the overall communication time, thus achieving faster and more efficient data transmission.…”

“…In the same year, a cyclic remote state preparation (CRSP) scheme [25] for circularly preparing three known single-qubit states with the control of one supervisor was also presented. Later, other types of CQT [26][27][28][29] and CRSP [30][31][32][33] schemes had been reported. But in these works, [24][25][26][27][28][29][30][31][32][33] two neighboring observers cannot exchange their states with each other, they only teleport states in one direction.…”

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.

This study investigates the effect of noise on two-qubit quantum teleportation through a four-qubit entangled channel theoretically. Therefore, in this study a comparison of two states of teleportation through ideal and noisy channel was carried out. The noisy channel can have the effect of bit-flip channel and phase-flip channel. From these two effects, it is found that the channel transforms in-to a mixed state. If the noise is neglected, the channel is pure state. Then, this channel is measured and fidelity is calculated. The fidelity of an ideal environment is 1. This indicates that the teleportation was successfully sent and at the same time confirms the teleportation behavior under ideal conditions. In noisy environments, fidelity can be less than 1. Two factors in noisy environment that affect fidelity are noise factor (p) and the orginal parameter states (transmission coefficients). In this calculation, for the bit flip noise, we observed that as the values of the coefficient values of transmitted state increase, the fidelity value increases. Meanwhile, for the phase flip noise, we observed that as the values of the coefficient values of transmitted state increase, the fidelity value decreases.

“…It is a technique for transfer of unknown quantum information from one location to a distant location through a previously shared entanglement between the sender and the receiver. Since then, a series of modified quantum teleportation protocols such as controlled teleportation [2][3][4][5][6][7][8][9], bi-directional teleportation [10][11][12][13][14][15][16], probabilistic teleportation [17][18][19][20][21][22], cyclic teleportation [23][24][25][26][27][28], multi-hop teleportation [29][30][31][32][33] and so on were developed in course of the last three decades which are applicable to a very wide variety of quantum states.…”

In this paper we discuss a quantum multi-tasking protocol for preparation of known one-qubit and two-qubit states respectively in two different locations. The ideal remote state preparation protocol is discussed in the first place in which a five-qubit entangled state is utilized. The design for the preparation of such entanglement is also presented and run on IBM quantum composer platform. The effects of three types of noises on the protocol are discussed and in all these cases the reduced fidelities of the process are calculated. The variations of these fidelities with respect to different parameters are analysed.
