英文摘要： Compared with the traditional communication method, quantum communication has its absolute safety characteristics. Quantum communication has great prospect application value in national security, financial and other information security field. Quantum entanglement is the key resource in quantum information. Compared with discrete variable entanglement, continuous-variable entanglement has its unique advantage, such as its high detection efficiency. Due to this reason, people have paid much attention to continuous-variable entanglement. With the rapid development of quantum information science, how to produce multipartite, especially multicolor continuous variable entangled optical fields，used in optical fiber communication and quantum storage wavebands， becomes more and more important. So the main research content of this project is how to produce multicolor continuous variable entangled optical fields..There are two main research contents ：1) The generation of multicolor continuous variable entangled optical fields using cascade nonlinear process based on optical superlattice；2) The generation of multcolor continuous variable entangled optical fields using coupled waveguide array based on optical superlattice；
