AOSense

AOSense is a Sunnyvale, California quantum sensor company founded in 2004 as a spin-out from Mark Kasevich's Stanford University atom interferometry group. The company develops cold-atom inertial sensors — accelerometers and gyroscopes — that use laser-cooled rubidium or cesium atoms as quantum test masses, achieving measurement precision orders of magnitude beyond classical MEMS-based inertial units. Unlike classical accelerometers that use mechanical proof masses subject to drift, AOSense instruments exploit the wave nature of matter: atoms in free fall form matter-wave interferometers whose
