Abstract
The gravitational field is a cornerstone in geophysics,providing crucial insights into the Earth's inner structure,seismic activity,groundwater resources,the planet's form,and its evolutionary narrative.The quantum gravimeter,a cutting-edge device for measuring absolute gravity,has been meticulously designed leveraging the exquisite precision of quantum measurement technology.It boasts unparalleled sensitivity coupled with unwavering stability,making it supremely suitable for the sustained,uninterrupted surveillance of the Earth's gravitational field.Across three decades,the quantum gravimeter has matured from a mere laboratory concept to a highly dependable apparatus on the cusp of widespread adoption.This paper examines the foundational principles underpinning quantum gravimeters,synthesizes the most recent scholarly developments,and discusses their geophysics applications.Moreover,it projects a visionary outlook on the prospective evolution of quantum gravimeters,underscoring their capacity to redefine our comprehension of the Earth's gravitational dynamics.
