“…(1) The efficiency of our scheme is 32%, which is relatively higher than those of the schemes in [16,[23][24][25]30,32]. Besides, our scheme has a larger transmission capacity than the other schemes because the sequentially increasing qubits could carry more information via the transmission in the scheme.…”

“…(4) Another remarkable advantage of our scheme is that the protocol can be employed to send multiple quantum information among multiple players either in an asymmetric manner. Compared with [16,[23][24][25]30,32], our scheme can realize the system having N > 3 observers. When the value of N is specified, we can construct anyone of all possible quantum channels.…”

“…In recent years, some RSP schemes that operated in noisy environments have been proposed [26][27][28][29]. In 2018, Sun [30] put forward an asymmetrically controlled two-way joint RSP in a noisy environment for the preparation of single and three equatorial states. The deterministic hierarchical remote state preparation of a two-qubit entangled state employing a Brown state in a noisy environment was proposed in 2020 [31].…”

As research on quantum computers and quantum information transmission deepens, the multi-particle and multi-mode quantum information transmission has been attracting increasing attention. For scenarios where multi-parties transmit sequentially increasing qubits, we put forward a novel (N + 1)-party cyclic remote state preparation (RSP) protocol among an arbitrary number of players and a controller. Specifically, we employ a four-party scheme in the case of a cyclic asymmetric remote state preparation scheme and demonstrate the feasibility of the scheme on the IBM Quantum Experience platform. Furthermore, we present a general quantum channel expression under different circulation directions based on the n-party. In addition, considering the impact of the actual environment in the scheme, we discuss the feasibility of the scheme affected by different noises.

We investigate the influence of noisy environment on the remote preparation of the multi-qubit equatorial state, and specifically deduce the final states and fidelities of the remote preparation of the three-qubit and four-qubit equatorial states under diverse types of noisy environment, namely amplitude damping, bit flip, phase damping, phase flip, bit-phase flip, depolarization and non-Markov environments. The results show that when the decoherence factors of the front six noise are equal, the influence degrees of phase damped noise, bit flip noise, phase flip noise and bit-phase flip noise are similar, while the information loss caused by amplitude damped noise and depolarizing noise is less. In particular, the bit flip noise and depolarizing noise may have more complex effects on the remote state preparation (RSP) schemes depending on the phase information of target states, even the ideal cases that the fidelity values are always 1 for specific phase relations. In the non-Markov environment, owing to the back and forth of information between the environment and systems, fidelities exhibit oscillating behavior and the minimum value may stay greater than zero for a long evolutionary time. These results are expected to have potential applications for understanding and avoiding the influence of noise on remote quantum communication and quantum networks.

“…Li et al [35] in 2018 proposed a scheme for bidirectional controlled remote state preparation of an arbitrary two-qubit state, where a nine-qubit entangled state is used as a quantum channel. Sun et al [36] in 2019 studied BQT under noisy environment and proposed a protocol for asymmetric bidirectional controlled teleportation by using nine-qubit entangled state in noisy environment. Shi et al [39] in 2019 proposed two symmetry BQT schemes by using a bi-photon Bell-class hyper-entangled state as a quantum channel.…”

In this paper, a theoretical scheme for bidirectional quantum teleportation by using a four-qubit GHZ state and two Bell states as a quantum channel is proposed. In this scheme, two arbitrary single-qubit quantum states and an unknown three-qubit state can be mutually transmitted between the two communication participants Alice and Bob. The quantum state information can be transmitted if Alice performs four single-qubit measurement operations on her qubits and Bob carries out a four-qubit joint measurement on his qubits, respectively. Then both Alice and Bob can reconstruct the target quantum state by means of appropriate unitary operations. Then we take comparisons with the other bidirectional quantum teleportation protocols in five aspects of quantum information bits transmitted, necessary operations, consumption of quantum resource, consumption of classical resource and intrinsic efficiency. Furthermore, we use channel authentication method to ensure the channel security and prove that our protocol can withstand four attack scenarios. It is concluded that our scheme has significant advantages of more qubits number transmitted, higher intrinsic efficiency and high security.
