英文摘要： As an important field in qauntum information science, quantum network communication has made a rapid development in recent years. PON network, a critical technology of the access network, has already occupied a large market share. It is also a means of integration of optical networks and quantum communication. In order to solve the security problems in PON network, the quantum anonymous communication becomes a hotspot in quantum communications.This project is planned to investigate the features of integration of quantum anonymous communication with non-maximally entanglement, hyper-entanglement, and hybrid entanglement. It aims to design several quantum anonymous communication schemes based on the principle of quantum entanglement, which solve the security issues of PON network. The contributations of this project are as follows: Firstly, we study the integration of several quantum entanglements, such as non-maximally entanglement, hyper-entanglement and hybrid entanglement, with PON network in order to clarify the machanisms of the quantum anonymous communications. Secondly, we design the corresponding quantum anonymous communication schemes using the non-maximally entanglement, hyper-entanglement, and hybrid entanglement measurements and analyze its security. Finally, we optimize these schemes while we analyze
