Quantum Sensing for Navigation and Guidance with Emerging Technologies

Quantum inertial sensors based on cold atom interferometry have been demonstrated to measure acceleration and angular velocity with excellent sensitivity and long-term stability. Significant efforts are underway to apply them in real-world environments. With the goal of elucidating the path to a compact field-deployable quantum inertial measurement unit that uses a 3-axis quantum accelerometer and a 3-axis quantum gyroscope, we present a multifaceted approach based on high data rate atom interferometry with a grating magneto-optical trap, time-multiplexed multi-axis inertial sensing, photonic integrated circuit laser systems, and membrane photonic platforms for guided atom interferometry with evanescent field modes.
