Research On Cyclic Quantum Teleportation Based On High-dimensional Entangled States

Quantum information is a new discipline combining quantum mechanics and classical informatics.With the advent of globalization and internet,information security incidents are increasing year by year.Quantum teleportation technology is favored by scholars all over the world in the field of information security.Quantum teleportation is one of the most important fields in the application of quantum information.It is different from the traditional classical communication mode,with the principle of uncertainty and quantum non-cloning theorem of the main advantages,can achieve unconditional secure communication.Based on the background of big data and quantum network,with the help of operator theory and the important mathematical basis and tools of operator algebra,this paper studies the related problems of cyclic quantum teleportation in high-dimensional systems.The main elements are as follows:1.Cyclic quantum teleportation of a single-particle high-dimensional stateTwo schemes of cyclic quantum teleportation are designed.First,using a six-particle quantum channel,cyclic quantum teleportation with three agents can be realized based on Bell state measurement.Second,under the control of the fourth party,the quantum channel of seven-particle can be used to realize controlled quantum teleportation with three agents.Both schemes can be extended to the case of cyclic quantum teleportation with 9)? 3 agents.2.Cyclic quantum teleportation of a multi-particle high-dimensional stateTwo schemes using different measurement methods are designed.First,the Bell state measurement can be used to realize the cyclic quantum teleportation;second,the cyclic quantum teleportation can be completed by the single particle measurement.Both schemes can be extended to multi-particle high-dimensional probabilistic cyclic quantum teleportation with equal total probability of success.3.Analyze the feasibility,resource consumption and efficiency of schemesOn the one hand,the schemes involved in the paper are experimentally feasible and safe.On the other hand,the efficiency of the scheme is analyzed to illustrate the advantages of the scheme.
