Quantum computing is the next-generation technology for future human society. This article aims to give a comprehensive and in-depth analysis of the global development status of quantum computing. First, the latest research hotspots of quantum computing are reviewed. Then multiple bibliometric metrics were used to analyse the current development status, research hotspots, technological trends, and the contribution of authors, institutions, and countries in quantum computing from 2016 to 2020. The results confirm that quantum computing is still under development, with the United States and China in the leading position, from where most critical scholars came. The most important institutions are scattered in the United States, China, and France. The characteristics of international cooperation, research impact, topics with the highest Prominence percentile, distinctive keyphrases, and leading source journals within the field were also analysed. The results may provide a quantitative basis for scientific research and decision-making in quantum computing.
