Leveraging the nature of quantum phenomena, quantum technologies are advancing rapidly in computing, communication, and sensing. Quantum inertial sensors based on light-pulse atom interferometry are powerful tools for precision measurements, navigation, geoscience, and civil engineering. By contrast to classical sensors, atom interferometers use photon momentum to coherently split and recombine matter waves. Since the laser wavelength precisely determines photon momentum, atom interferometers are highly accurate and have demonstrated unprecedented sensitivity and stability. In this talk, I will present compact and versatile atom interferometers for measuring the local gravity field and sensing multi-axis accelerations and rotations. With simplicity and sensitivity, our technology paves the way for deploying quantum sensors in field applications.
