量子光学与量子信息领域中的中国

为了解世界量子光学与量子信息的发展态势,认识中国在国际量子光学与量子信息领域中的地位,针对量子光学与量子信息领域的主要学科,按照美国光学学会(OSA)数据库量子光学与量子信息的13个分类,检索了SCI数据库1991年至2006年的数据。用文献计量学、科学计量学和情报分析方法研究国际量子光学与量子信息领域各学科的发展速度,比较各主要国家量子光学与量子信息论文的数量,从而使中国量子光学与量子信息领域的科学家有一个量的判断,多一些思维空间,多一种观察视角。结论认为,量子光学与量子信息是21世纪最具生命力的新兴学科之一,中国在理论和实验两方面都做出了一些重要的具有创新性的贡献,论文被引频次的世界贡献率呈增长态势。

China in quantum optics and quantum information

In order to investigate the development of quantum optics and quantum information all over the world and to evaluate China's present status in the field,the data from the SCI database(1991~2006) was indexed based on 13 subjects categorized by Optical Society of America(OSA).The methods from literature metrology,scientific metrology and information analysis were used to measure the development speed of these disciplines and to compare the number of research papers of those leading countries.Therefore,scientists in China can have a quantitative judgment,a multi-dimensional thinking and more angles of observation.The conclusion is that the field of quantum optics and quantum information is one of the most viable new sciences in the 21st century.China has made some important innovative contributions in both theory and practice,which has been illustrated by the increasing tendency in reseaarch paper citation.
