  Weak measurement has enabled fundamental studies in both experiment and
theory of quantum measurement. Numerous researches have indicated that weak
measurements have a wide range of application and scientific research value. In
our work, we used bibliometric methods to evaluate the global scientific output
of research on Weak measurement and explore the current status and trends in
this field from 2000 to 2020. The R bibliometric package was used for
quantitative and qualitative analyses of publication outputs and author
contributions. In total, 636 related articles and reviews were included in the
final analysis. The main results were as follows: The number of publications
has increased substantially with time. Physical Review A was the most active
journal. The country and institution contributing the most to this field were
The United States and University Rochester respectively. The analysis of the
conceptual structure of keywords indicated that weak measurements were involved
a variety of metrology, quantum communication, and nonclassical features of
quantum mechanics. Our bibliometric analysis shows that weak measurement
research continues to be a hot-spot. The focus has evolved to study quantum
information and amplify weak signals.
