要旨

General relativity has been widely accepted as the standard theory of gravity, supported by tests in weak gravitational fields. However, many extended theories of gravity have been proposed to address fundamental challenges such as the unification of gravity with quantum theory. Testing these theories in unexplored gravitational regimes provides crucial insights into the nature of gravity.
Advancements in quantum measurement techniques have enabled precision tests of gravity.
In particular, gravitational-wave observations by LIGO-Virgo-KAGRA have enabled precision tests of strong-field gravity, providing a means to probe deviations from general relativity that may arise from low-energy modifications of quantum gravity. At the same time, the development of quantum measurement techniques offers the possibility of experimentally verifying the quantum nature of gravity at low energies.
In this talk, I will discuss how quantum measurements contribute to testing gravity, focusing on gravitational waves as a key probe.
