Abstract: 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.

Key words: Quantum Sensing, Bibliometrics, Strategic Layout, Single-photon Source
