“…where q s denotes the number of states to be transmitted, q u indicates the quantum resource consumption, and b t means the classical resource consumption. Based on the equation, the efficiency of the scheme is: Table 2 presents a comparison with other schemes [15], [17], [36]- [39] in terms of six aspects, including the type of scheme (TOS), the number of qubits transmitted (NQT), the quantum resource consumption (QRC), the classical resource consumption (CRC), the auxiliary operations (AO), and the efficiency (κ). From TABLE 2, the following conclusions can be drawn: 1) The efficiency of the proposed scheme is slightly better than those of the schemes in [15], [36]- [39], but it is no better than the scheme in [17].…”

“…In 2018, Zhang et al [36] and Sang et al [37] presented two schemes for cyclic RSP by respectively using three multi-qubit GHZ-type states and a ten-qubit entangled state as the quantum channel. In 2018, Fang et al [38] and Wu et al [39] each presented one scheme for bidirectional and hybrid quantum communication, which allowed the sender and receiver to exchange their states with each other, whether they knew the state or not. Different from QT or RSP schemes, these two schemes are hybrid protocols for quantum communication, and the channels are multipurpose.…”

“…Based on the schemes in [15], [17], [36]- [39], we propose a scheme for hybrid double-channel quantum communication for three parties by using the product state of three Bell-state and three GHZ-state as the quantum channel. The three participants, Alice, Bob, and Charlie, are all senders and receivers, and there are two communication channels, QT and RSP, between each pair of them.…”

In this paper, a scheme for cyclic hybrid double-channel quantum communication is proposed by using the product state of three Bell states and three Greenberger-Horne-Zeilinger (GHZ) states as the quantum channel. It shows that Alice teleports a single-qubit state to Bob and prepares a single-qubit state for Charlie, Bob teleports a single-qubit state to Charlie and prepares a single-qubit state for Alice, while Charlie teleports a single-qubit state to Alice and prepares a single-qubit state for Bob. The quantum channel is constructed by using Hadamard (H) and Controlled-NOT (CNOT) operations. Participants reconstruct the desired states by performing Bell-state measurements, single-qubit measurements, and unitary transformations. Compared with existing schemes, this new scheme improves the efficiency and capacity of quantum communication because it constructs a cyclic and bidirectional quantum communication and simultaneously supports two communication protocols, quantum teleportation and remote state preparation. Only single-qubit measurements, two-qubit measurements, and basic unitary transformations are utilized in the scheme, so our operation complexity is lower than others. Thus, the scheme is likely to be implemented through physical experiments in the future. Besides this, we discuss the impact of noisy environments (amplitude-damping, phase-damping noise, bit-flip noise, and phase-flip noise) in the scheme and calculate the fidelities of the output states. It is demonstrated that the fidelities only depend on the coefficients of the initial state and the decoherence rate.

In this paper, a novel asymmetric controlled bidirectional remote preparation scheme is proposed. In our scheme, Alice and Bob are not only the senders but also the receivers with the control of Charlie. By using the eleven-qubit entangled state as the quantum channel, Alice prepares an arbitrary two-qubit equatorial state for Bob and Bob prepares an arbitrary three-qubit equatorial state for Alice simultaneously. Firstly, we give the construction process of the quantum channel. Secondly, the whole recovery operations are given. Alice and Bob can recover the prepared state determinately. Thirdly, we consider the effect of the noisy environment (amplitude-damping and phase-damping) in our scheme and calculate the fidelities of the output states. Finally, since our scheme does not need additional operations and auxiliary qubits, the efficiency of our scheme is higher than that of the previous schemes.

We present an asymmetric controlled bidirectional remote preparation scheme under the control of Charlie, where Alice transmits an arbitrary single-qubit equatorial state to Bob and Bob transmits an arbitrary three-qubit equatorial state to Alice. First, the quantum channel is constructed by using Hadamard (H) and CNOT operations. Second, we consider our scheme in the noiseless environment and construct the appropriate measurement bases. In addition, the participants can recover the prepared states through implementing the corresponding recovery operations determinately. Third, we discuss our scheme in five types of noisy environments (amplitude-damping, phase-damping, bit-flip, phase-flip, and depolarizing noisy environment). The fidelities of the output states are calculated, which depend on the coefficients of the prepared states and the decoherence rates. Finally, some discussions and conclusions are given. Compared with previous schemes, our scheme does not need additional operations or auxiliary qubits. So it is slightly more efficient. INDEX TERMS Asymmetry, controlled bidirectional remote preparation, noisy environment, fidelity.
