Future Inertial Atomic Quantum Sensors: State of Art

Abstract

A collaboration between European research groups is developing novel atomic inertial quantum sensors based on matter-wave optics and Raman interferometry. For this purpose we are implementing a gravimeter and a gyroscope using ultra cold atoms as test masses. Inertial quantum sensors could represent a new tool for the precise detection of faint forces and tiny rotations. According to the principle of these sensors, the measured physical quantity will be converted into a frequency, which can be measured with highest accuracy. The items of atom interferometry will range from fundamental physical tests to many practical applications such as: local gravity measurements, allowing a precise underground mapping, and space navigation. In this contest the main goal is to realize modular and portable systems.
