In complex quantum network communication systems, the requirement for the abilities of quickly processing data and rapid response on service becomes increasingly intense. For example, in a complex network topology structure, we hope to find a target vertex, side or clique as soon as possible from a source vertex, so an efficient search mechanism needs to be constructed. This project intends to further study the search mechanism of quantum walk. Then based on different types of search targets and performance requirements, this project explores the search mechanism, algorithm (scheme) design, efficiency analysis and calculation model of quantum search mechanism with quantum walk, in hope to solve the problem of searching target speed and efficiency in the quantum network communication system through the way of quantum walk search. The innovation of this project is to overcome the application limitation of quantum search mechanism and realize the quantum search algorithm applied to the topological structure of complex quantum network according to the quantum parallelism and quantum interference effect of quantum mechanics and the advantages of quantum walks. It can also provide a scientific and practical way for the integration of quantum search technology and modern quantum network communication systems, which may figure out potential problems on quick response to search problems both theoretically and technically.
