Abstract: Quantum computation, an important technology that breaks through the limit of classical computation, has become a key point in the scientific and technological layout of various countries. The related research and application continue to advance globally, and the relevant bibliometric analysis of Sino-foreign cooperation papers can help us to deeply understand China’s international cooperation in this field. In this paper, we searched the relevant literature through the Web of Science database, and used visualization tools such as CiteSpace and Bibliometrix to analyze the number of Sino-foreign collaborative papers, keyword clustering, collaborative institutions, core researchers, and funding organizations. The results show that the number of publications in the field of quantum computation is generally on the rise, but the development of Sino-foreign cooperation has been restricted in recent years; the directions of cooperative research include but are not limited to quantum fundamental theory, quantum algorithmic models, and physical implementation of quantum computers, etc., and the popular directions of research are closely connected with the field of artificial intelligence; China has a number of cooperative institutions and researchers with international influence, and the cooperation funding is led by the National Natural Science Foundation of China (NSFC).In the future, China should actively deploy quantum computation at both national and international levels, and continue to deepen its efforts in the field of quantum computation.
