DESCRIPTION:Brynle Barrett \, University of New Brunswick\n\n
Robust and accurate a
cceleration tracking remains a challenge in many fields. For geophysics an
d economic geology\, precise gravity mapping requires onboard sensors comb
ined with accurate positioning and navigation systems. Cold-atom-based qua
ntum inertial sensors can provide such high-precision instruments. However
\, current scalar instruments require precise alignment with vector quanti
ties such as gravity. This presents a significant challenge in mobile envi
ronments. \;In recent work\, we realized the first &ldquo\;vectorial&r
dquo\; quantum accelerometer \;by combining three orthogonal atom inte
rferometer measurements with a classical accelerometer triad. We demonstra
te acceleration vector tracking with
a 50-fold improvement in stability compared to our navigation-grade classi
cal accelerometers. \;In this talk\, I will give an overview of
our vectorial quantum sensor and discuss future work moving beyond scalar
quantum sensing.
