"Moving Beyond Scalar Quantum Sensing with Cold-Atom Interferometers"Brynle Barrett , University of New Brunswick [Host: Cass Sackett]
ABSTRACT:
Robust and accurate acceleration tracking remains a challenge in many fields. For geophysics and economic geology, precise gravity mapping requires onboard sensors combined with accurate positioning and navigation systems. Cold-atom-based quantum inertial sensors can provide such high-precision instruments. However, current scalar instruments require precise alignment with vector quantities such as gravity. This presents a significant challenge in mobile environments. In recent work, we realized the first “vectorial” quantum accelerometer by combining three orthogonal atom interferometer measurements with a classical accelerometer triad. We demonstrate acceleration vector tracking with a 50-fold improvement in stability compared to our navigation-grade classical accelerometers. In this talk, I will give an overview of our vectorial quantum sensor and discuss future work moving beyond scalar quantum sensing. |
