Quantum information science is a product of quantum mechanics and classical informatics.It inherits both the thinking mode of classical informatics and the unique technology of quantum itself.Especially in the aspect of quantum information transfer technology,quantum information breaks through the security and speed issues of classical information transmission with its unique properties.It is because of this nature of quantum that quantum information has had a tremendous development since its birth.Whether it is theoretical or experimental,it has made great breakthroughs in this field and has become a research hotspot for scientists at this stage.Entanglement is a property unique to quantum mechanics.It is also the essence of quantum information science and the basic requirement for the growth of various quantum information technologies.The quantum information transmission technology is also based on quantum entanglement.The most attention is given to quantum teleportation.Quantum teleportation has the advantages of high security,resource saving,and wide application.Therefore,the design of the quantum teleportation scheme has been proposed successively.Among them,the quantum teleportation scheme using the cluster state as the quantum channel has become a hot spot in recent research.This paper studies the information transmission based on the quantum entanglement theory,and here we mainly studied the quantum teleportation that utilizing cluster state as quantum channel.Firstly,this paper gives a brief overview of quantum informatics,introduces the growth process and significance of quantum teleportation,and briefly introduces the basic knowledge of quantum informatics,the definition,properties of quantum qubit,and the definition,properties,preparation of quantum entanglement,theoretical knowledge such as uncertainty principle and no-cloning theorem,commonly used quantum gates,etc.Secondly,we design an efficient quantum teleportation scheme based on the existing quantum teleportation scheme.In this scheme,we transmit a five-qubit state by utilizing a seven-qubit cluster state.After that,we performed a performance analysis and compared our scheme with the other two quantum teleportation schemes which were proposed before.By comparing,we find our scheme has higher efficiency.Then the overall analysis was performed.Thirdly,in response to the insufficiency of the previous scheme,we improved the previous scheme and proposed another quantum teleportation scheme.We propose a novel quantum teleportation protocol for eight-qubit state with a six-qubit cluster state as quantum channel.In this scheme,we utilize CNOT operation.Then,we have promoted the scheme to the N particle state.Finally,the paper concludes and looks forward.Quantum teleportation has become a hot spot for people with its unique advantages.The experiment of quantum teleportation has also made great breakthroughs.It is believed that quantum teleportation can be applied to all aspects of the world in the future.
