量子信息科技中的量子材料研究态势观察☆
Trend Observation of Quantum Materials in the Field of Quantum Information Science and Technology
[目的/意义] 通过分析量子信息相关量子材料领域的研究态势,为该领域的研究和管理决策提供信息支撑。[方法/过程] 以Web of Science科学引文索引数据库为数据来源,综合运用文献计量学、LDA主题模型以及共现网络分析法等多种研究方法,对量子信息科技中量子材料研究发展趋势、竞争态势、重点研究主题等进行深入分析。[结果/结论] 量子信息科技中量子材料研究处于快速发展阶段,相关研究数量呈稳步上涨的趋势,新的研究高峰可能尚未形成;美国、中国、德国、日本是该领域的主要研究国家;研究机构分布较为分散,高校占比最多近年来例如方向;从研究主题来看,目前主要集中在超导等主流材料、二维材料等新兴材料、以及底层关键量子技术等方向;近年来我国发展迅速,但研究积累较美国薄弱,超导材料、量子点、拓扑量子材料、金刚石、硅材料等较美国还有一定差距;我国优势机构当持续发挥技术应用方面的引领作用,加速量子信息产业发展底层关键材料和关键基础技术研发。
[Objective/Significance] By analyzing the research trends in the field of quantum materials, this study provides information support for research and management decision-making in the field of quantum materials. [Method/Process] This paper uses the Web of Science scientific citation index database as the data source and comprehensively applies various research methods such as bibliometrics, LDA topic modeling, and co-occurrence network analysis to conduct an in-depth analysis of the development trends, competitive situation, and key research topics in the field of quantum materials related to quantum information science. [Results/Conclusions] The research on quantum materials related to quantum information technology is still in a stage of rapid development, and the number of related research shows a steadily rising trend. A new research peak may not have yet formed; the United States, China, Germany, and Japan are the main countries conducting research in this field; research institutions are relatively dispersed, with universities having the largest proportion; in terms of research topics, the main focus on superconductivity and other mainstream materials, two-dimensional materials and other emerging materials, as well as the underlying key quantum technology; China's rapid development in recent years, but the research accumulation is weaker than the United States, for example, superconducting materials, quantum dots, topological quantum materials, diamond, silicon materials, and other directions compared with the United States there is still a certain gap; China's advantageous organizations should continue to play a leading role in the application of technology, accelerate the development of quantum information industry, the underlying key materials and key basic technology research and development.
