Abstract: Exploring the international research status, hotspots and future development trend of quantum computing is significant for China’s strategic deployment and technological planning. The literature related to quantum computing collected in the Web of Science database from 2007 to 2021 is taken as the research object. Based on bibliometric and content analysis methods, text mining and visualization analysis tools are used to explore the research status in this field from the dimensions of publication trend, major countries, institutions, researchers, hotspots, and development trends. Studies have shown that： quantum computing literature presents an increasing trend year by year; the United States ranks first in literature number and citations per article, and has strong scientific research strength; China has a group of influential institutions and scholars in this field, but the cooperation intensity between institutions is low; research hotspots are distributed in quantum algorithms, quantum computing models, the physical realization of quantum computers and the application of quantum computing; research frontiers focus on quantum computing model and the application in artificial intelligence, cryptanalysis and other fields.

Key words: quantum computing, bibliometrics, content analysis, knowledge mapping, research hotspot

摘要： 探究量子计算领域国际研究态势、研究热点和发展趋势对我国在该领域的战略部署和科技规划具有重要的借鉴和参考意义。以Web of Science数据库2007—2021年收录的量子计算领域的文献作为研究对象，基于文献计量和内容分析的方法，利用文本挖掘和可视化分析工具从发文趋势、主要国家、研究机构、研究人员、研究热点和发展趋势等维度探究该领域的研究态势。研究发现，量子计算领域发文量总体上呈现逐年递增趋势；美国的发文量和篇均被引频次位居首位，拥有雄厚的科研实力；我国在该领域拥有一批有影响力的研究机构和学者，但是机构间合作强度较低；研究热点主要分布在量子算法、量子计算模型、量子计算机的物理实现以及量子计算的应用等方面；研究前沿主要聚焦在量子计算模型研究以及量子计算在人工智能、密码分析等领域的应用。
