Abstract

Abstract Multi-party quantum communication has gradually attracted widespread attention. To realize the perfect transmission of quantum states among multiple participants, a novel multi-party controlled cyclic remote preparation protocol for arbitrary single-qubit states with three senders is proposed. With the permission of one controller, each sender can transmit an arbitrary single-qubit state to its neighbor. In addition, we give a universal protocol for multi-party controlled cyclic remote preparation of arbitrary single-qubit states in the case of multiple senders, which can realize deterministic cyclic preparation of multiple quantum states in one direction. The scheme shows that the communication task can be successfully achieved only if all senders cooperate with the controller, and there is no need for the senders to employ information splitting and additional operations before performing measurements. Finally, we discuss the cyclic remote preparation protocol with three senders under five types of noisy environment, and the closeness between the output state and original state is measured by calculating fidelity.

A Scheme for Controlled Cyclic Asymmetric Remote State Preparation in Noisy Environment

Nan Zhao, Tingting Wu, Yan Yu +1 more

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.

Controlled Cyclic and Bidirectional Hybrid Quantum Communication of Arbitrary Two‐Qubit States

Li‐Hua Gong, Xiu‐Bo Chen, Gang Xu +1 more

Abstract 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.

Controlled cyclic joint remote state preparation of arbitrary single-qubit states

Zhihang Xu, Min Jiang

A novel scheme for controlled cyclic joint remote state preparation (CCJRSP) is proposed where arbitrary single-qubit state can be mutually transmitted between three communication participants Alice, Bob and Charlie under the control of the supervisor David. In our scheme, one participant can reconstruct the desired states by performing POVM measurement and basic unitary transformation with the help of other two participants in a cyclic manner. In addition, one non-maximally entangled channel is utilized in this work. Hence, the requirement for the quantum channel is reduced.

Protecting cyclic controlled remote preparation of qudit states in a chain network

Si Jin, Song-Ya Ma, Yu Lu

Abstract We concern on the cyclic controlled remote preparation of qudit states in a chain network. By choosing proper entanglement resources, we first propose a unidirectional scheme where single-qudit states can be deterministically prepared clockwise among multiple users. Each sender executes a positive operator-value measure under the elaborately constructed basis and a projective measurement (PM) under the generalized X basis, while the controller carries out a PM under the generalized Z basis. The corresponding receiver can restore the target state by executing recovery operations which is deduced by universal formulas. Then, we present a bidirectional scheme such that each sender can prepare two single-qudit states in both clockwise and counterclockwise directions. It is worth stressing that network coding is applied at the controller’s site to reduce the classical communication cost. The schemes are further extended to arbitrary multi-particle systems. Additionally, we consider the impact of amplitude damping noise and phase damping noise, and employ the strategy of weak measurement to counteract noise.

Controlled cyclic remote state preparation of arbitrary qubit states

M. Wang, Chui‐Ping Yang, R. Mousoli

Quantum secure communications could securely transmit quantum information by using quantum resource. Recently, novel applications such as bidirectional and asymmetric quantum protocols have been developed. \n \nIn this paper, we propose a new method for generating entanglement which is highly useful for multiparty quantum communications such as teleportation and Remote State Preparation (RSP). As one of its applications, we propose a new type of quantum secure communications, i.e. cyclic RSP protocols. Starting from a four-party controlled cyclic RSP protocol of one-qubit states, we show that this cyclic protocol can be generalized to a multiparty controlled cyclic RSP protocol for preparation of arbitrary qubit states. We point out that previous bidirectional and asymmetric protocols can be regarded as a simpler form of our cyclic RSP protocols.

Enhanced controlled cyclic hybrid quantum communication with multi-supervisor architecture in noisy environments

Fei Huang, Miao Liu, Jiangang Tang +3 more

Abstract Controlled cyclic hybrid quantum communication (CCHQC) has emerged as a promising framework for secure multi-party quantum networks. We propose a novel multi-supervisor CCHQC protocol that enhances security and fault tolerance while maintaining high-dimensional state transmission capabilities. Our protocol enables simultaneous cyclic teleportation of arbitrary unknown qudit states and remote state preparation of known states under multiple controller supervision. By employing a carefully designed multi-partite entangled channel and optimized measurement operators, we achieve unit success probability in noiseless conditions. Furthermore, we introduce a comprehensive noise mitigation strategy combining weak measurement, environment-assisted measurement, and quantum error correction techniques to combat amplitude damping noise. Through detailed performance analysis, we demonstrate that our protocol outperforms existing schemes in terms of intrinsic efficiency, security, and roCoverLetter.texbustness against decoherence. The proposed architecture provides a scalable solution for practical quantum network implementations in noisy environments.
