Analysis on the Development Strategies and Trends of Quantum Sensing

以量子信息科学的重要分支——量子传感为研究对象,结合文献计量和典型调查法,探究量子传感领域的战略布局及研究方向。研究表明,量子传感近十年发展迅速,发文数量、研究人员数量均快速增加,研究热度持续攀升。宏观层面:美国、德国、中国、日本、英国等国家竞争激烈,美德英日等相继推出国家战略规划引导量子传感研发。中观层面:乌尔姆大学、麻省理工学院、中国科学技术大学等发文数量居全球前三;乌尔姆大学、哈佛大学和麻省理工学院等在发文机构的合作网络中处于核心地位;以乌尔姆大学为代表的主要机构多重视固体单光子源研究,注重学科交叉、科研合作。研究方向演化方面:近十年基于冷原子体系的量子传感依然保持着较高的研究热度,同时基于固态单光子源的量子传感迅速成为研究热点。

Strategic layout and main research directions of quantum sensing,an important branch of quantum information science,are explored by combining bibliometrics and typical survey methods.Research shows that quantum sensing has developed rapidly in the past decade,with the number of publications and the number of researchers increasing rapidly,and the popularity of research continues to rise.1)Macro level:The United States,Germany,China,Japan and Britain compete fiercely,and the United States,Germany,Britain and Japan have successively launched national strategic plans to guide related research.2)Meso level:The Ulm University,Massachusetts Institute of Technology,and University of Science and Technology of China rank among the top three in terms of the number of publications,whlie Ulm University,Harvard University and Massachusetts Institute of Technology are at the core of the cooperation network of institutions.The main institutions represented by Ulm University pay more attention to the research of solid single-photon sources,and to interdisciplinary and scientific research cooperation.3)Research direction evolution:Quantum sensing based on cold atom systems has maintained a high degree of research interest in the past decade,while quantum sensing based on solid-state single-photon sources has rapidly become a research hotspot.
