A new generation of operational high-performance Quantum Sensors: Quantum Technologies outside of the laboratory

报告内容摘要

After 30 years of academic research in cold-atom sciences, intensive developments are being conducted to improve the compactness, the reliability, and the ease of use of experimental set-ups in Quantum Physics. One objective is to transform these into operational instruments operating outside of the laboratory by non-specialists.

This seminar will be dedicated to the presentation of the R&D and deployment activities of the French company Muquans in terms of high-precision Quantum Sensors. We will present in detail the principles of operation and the main features of our technology. In particular, we will review the latest results of the world’s first commercial Absolute Quantum Gravimeter and cold-atom atomic clock provided by Muquans. This will allow us to illustrate the performances of a new generation of turnkey research-grade laser sources specially developed for Quantum Sciences.

报告人简介

Dr. Jean Lautier-Gaud conducted his research in the field of atom interferometry applied to inertial sensing at LNE-SYRTE laboratory (French National Metrological Institute for Time/Frequency). He worked on a project aiming at simplifying cold-atom physics experimental set-ups, in order to facilitate their utilization and transfer these technologies to the Industry. He developed a compact quantum accelerometer dedicated to on-field measurements. This work led to set the world record in terms of sensitivity to acceleration for an instrument operating without any vibration isolation platform. Jean Lautier-Gaud also demonstrated the possibility to hybridize classical and quantum accelerometers, in a similar way than it is achieved for atomic clocks. This represents a crucial step towards the onboard operation of quantum inertial sensors, in space for example.
