Description
Absolute gravimeters based on falling corner-cube reflectors have been a cornerstone of geophysical research and exploration for decades. On the other hand, quantum gravimeters use matter-wave interferometry with a free-falling cloud of laser-cooled atoms to measure gravity down to the $10^{-9}$ g level. These instruments have demonstrated excellent sensitivity and stability over several months, making them ideal for detecting low-frequency gravity signals. Commercial quantum gravimeters are now available on the market, but there has been surprisingly little work to develop them in Canada. In this talk, I will discuss progress toward building Canada’s first portable quantum gravimeter at the University of New Brunswick. I will also provide an overview of its functionality and its key advantages over traditional technologies for applications in geophysics and geodesy.
