[Abstract]:In order to improve the performance of information system by using entangled signal instead of radio signal to break the classical limitation, the necessity of developing entangled microwave technology is expounded, and the development course of path entangled microwave preparation is reviewed. Secondly, four kinds of path entangled microwave signal preparation schemes are summarized: superconducting 180 掳hybrid loop, Wilkinson power divider, Josephson parametric converter and microwave band Hong-Ou-Mandel effect. On the basis of the detailed description of the microwave beam splitter used in this paper, the preparation scheme of the existing path entangled microwave signal is analyzed from the two aspects of the experimental device and the basic principle, respectively, by using the method of comparative analysis. Then the expression of the path entangled microwave signal generated by each scheme is given. Finally, the advantages and disadvantages of each scheme are analyzed concretely, the main factors restricting the development of quantum entangled microwave technology are summarized, and its broad development prospect is pointed out. The future research direction of preparing path entangled microwave signal is prospected.
