The Research Of Quantum Teleportation Scheme

Quantum information science is a new discipline by the intersection of quantum mechanics and information science combination formed,is mainly composed of two parts of quantum communication and quantum computation and quantum communication mainly includes quantum teleportation(QT),quantum dense encoding(QDC),quantum secret sharing(QSS)and so on.And QT is the most important part of quantum communication,which uses the physical properties of quantum,through the sharing of quantum entanglement pairs,and as a quantum channel to achieve the transmission of information.QT has obvious advantages compared with classical communication,breaking the limitations of classical information in information capacity and security.In recent years,with the joint efforts of a large number of scholars and researchers,quantum communication has made great progress in theory and experiment.Through the introduction of QT from the theoretical and physical realization of two aspects,and analysis of the corresponding QT scheme,to understand it in the quantum entangled particles as the carrier of information,through Bell based measurement and so on particle is operation,realize the transfer of quantum states.The main results of this paper are as follows:(1)Based on Tan and Chen theory study,in the analysis of continuous hard work and repeatedly proposed a new QT scheme,this scheme through the sharing of eight particle entangled quantum channel,the successful implementation of the transfer of quantum state,and the scheme is a two-way asymmetric,which both sides of communication at the same time the transmission of quantum states,quantum number of transmission is different.(2)Based on QT theory on a great deal,through the study of QT learning scheme based on cavity QED,we proposed a new QT scheme,and through the analysis and research of the scheme,the scheme can be realized in physical theory.
