Abstract

This paper reports recent remarkable achievements of cold-atom technologies and related operational devices in the area of Quantum Sensing and Metrology. We will present in detail the status of the Absolute Quantum Gravimeter (AQG) that has left the laboratory for geophysical studies. The AQG is an industry-grade commercial gravity sensor which today meets the objective to provide a gravimeter based on atom interferometry with laser-cooled atoms as a mobile turn-key device. We report on an operational stability of continuous absolute measurements of g at the 10-10 level in various types of environment during month-long continuous acquisition periods. The first unit of the AQG has traveled more than 7000 km, so we will comment on the last measurement campaigns and comparisons performed by the AQG. These have in particular validated the repeatability of the measurements at the 10-9 level, the ease of use and the robustness of such technology. This paper will also be the occasion to describe in more details the maturity of several key technologies such as intelligent integrated laser systems that can help Quantum Technologies with cold-atoms taking-off for a wider range of applications in Quantum Computing, Quantum Simulation and Quantum Communication.
