Quantum Information Splitting Scheme of Arbitrary Three-Qubit State by Using a Four-Qubit Cluster State and a Bell State

Abstract

AbstractWith the rapid development of Internet technology, the confidentiality of information content and network security are facing severe challenges, and quantum teleportation ensures the absolute security of information transmission based on its basic characteristics. In this paper, we propose a scheme for quantum information splitting of arbitrary three-qubit state by using a four-qubit cluster state and a Bell state. The scheme only needs to perform two Bell state measurement operations and two single-qubit measurement operations, and Bob can reconstruct the transmitted arbitrary three-qubit state by means of appropriate unitary operations. Compared with other information splitting schemes of arbitrary three-qubit state, our scheme is characterized by higher transmission efficiency. Then we use channel authentication method to ensure the communication security of our scheme under different attack scenarios. Furthermore, we take comparisons with the other quantum information splitting schemes in five aspects of quantum information bits transmitted, necessary operations, consumption of quantum resource, consumption of classical resource and intrinsic efficiency. It is concluded that our scheme has significant advantages of higher intrinsic efficiency and high security.KeywordsQuantum communicationCommunication securityQuantum teleportationNetwork information securityChannel authentication
