Acceleration measurements with a diamond quantum sensor
Abstract
This project contributes to a large and ambitious goal of building a silicon-chip-based diamond quantum accelerometer and magnetometer which is sensitive, small, lightweight and low power. The dual mode sensing capability will enable low-drift inertial measurement for navigation in GPS denied environments in air, sea, and underground. Furthermore, with considerable efforts in developing new, autonomous space-based technologies, the combined sensitivity and size of this sensor could be coupled with CubeSat systems for precision navigation and remote sensing in space. Specifically, this project seeks to understand the fundamental response characteristics of a bench-top diamond magnetometer relative to changing magnetic field vectors from a magnetic test-mass which underpin the design for a new “quantum-classical” accelerometer. The key advantages stem from the fact that the diamond quantum sensor is able to operate at room-temperature and sense magnetic fields down to femto-Tesla/?Hz in a sub-mm^3 sensing volume. With this degree of sensitivity, we expect the mass-spring accelerometer would outperform any existing classical accelerometer available today. We will make use of our team’s broad-base of expertise in diamond quantum technology and silicon-chip technology to enable bridging between quantum and classical systems.
