“…Since bidirectional quantum teleportation protocol was first proposed in 2013, many bidirectional quantum teleportation protocols have been proposed. However, in these presented protocols, quantum information bits transferred by two communicating parties are generally two single-qubit states [16], [17], [21]- [24] a single-qubit state and a two-qubit state [20], [25], [26], two two-qubit states [27], [28], the aim of this paper is to increase the number of quantum information bits transmitted by communicating parties. So, it is an innovational theory to use a three-qubit entangled state and a single-qubit state as quantum information bits transmitted.…”

Quantum teleportation is considered as the most basic process of quantum communication. It is undoubtedly beneficial for the realization of quantum teleportation while transmitting the maximum number of quantum bits with the minimum number of quantum channel resources. An improved bidirectional quantum teleportation protocol based on a quantum channel of six-qubit cluster state is proposed. In this paper, the user Alice can transmit an unknown three-qubit entangled state to the user Bob, and at the same time, the user Bob can transmit an arbitrary single-qubit state to the user Alice by utilizing GHz-state measurement, bell-state measurement, single-qubit Von Neumann measurement, and unitary operations. Compared with other schemes in quantum resource consumption, necessary operation complexity including operation difficulty and intensity, classical resource consumption, quantum information bits transmitted, and intrinsic efficiency, our scheme has the remarkable advantages in transmitting more quantum information and possesses higher intrinsic efficiency.

“…Since then, the technique has attracted a great deal of attention from researchers, and various related schemes have been presented [4]- [7]. To improve the capacity and security of quantum communication, many variants of QT schemes were put forward, such as controlled QT (CQT) [8], [9], bidirectional QT (BQT) [10]- [13], and controlled BQT (CBQT) [14], [15].…”

“…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.
