Abstract: The progress of quantum information technology depends to a large extent on the maturity and development of traditional materials. In recent years, lithium niobate has become an important building-block material for quantum devices, which have great application potential in the field of quantum science and technology. The technical progress of various lithium niobate quantum devices such as quantum emitters, quantum repeaters, and single photon detector prepared based on lithium niobate materials has been combed. The advantages and disadvantages of these devices were summarized, and their main development trends in the future were prospected. This study has a good guiding role for the practical application of quantum devices based on lithium niobate in quantum information technology.
