Summary:

The LKB atom interferometry group (also at SYRTE, Observatoire de Paris) develops cold atom inertial sensors including the world's best gyroscopes and gravimeters. Key research (Geiger, Landragin et al.): (1) interleaved cold atom gyroscope with 3.75 Hz sampling and 800ms interrogation (record sensitivity); (2) cold atom gradiometer for gravity gradient mapping; (3) atom chip-based compact sources for inertial navigation; (4) quantum optimal control for robust matter-wave sensing. QAFCA project (PEPR Quantique) on quantum sensors for geoscience and navigation. Note: The main PI is Remi Geiger (CNRS) / Arnaud Landragin, both at SYRTE/Observatoire de Paris (PSL), but LKB atom interferometry team is at ENS site.

Summary:

Rémi Geiger (CNRS DR, SYRTE/Observatoire de Paris; IUF 2020) leads atom interferometry for inertial sensing. Research: (1) interleaved cold-atom gyroscope — world record 3.75 Hz sampling rate with 801ms interrogation time; (2) EQUIP-G Horizon Europe project for quantum gravimeter network deployment across Europe (2025); (3) ESA ODIN gyroscope for X-ray space mission; (4) entangled-atom tests of Einstein equivalence principle. Key figure in precision cold-atom inertial sensors. Note: formally at SYRTE (PSL/Obs. Paris), entered under ENS (same PSL network).

Summary:

Landragin directs SYRTE and its Cold Atom Interferometry and Inertial Sensors team, which develops light-pulse atom interferometers as absolute gravimeters and gyroscopes: the Cold Atom Gravimeter (CAG), whose single-laser pyramid-reflector design he co-invented and commercialized through the start-up Muquans (now Absolute Quantum Gravimeter, AQG), and continuously-operating cold-atom gyroscopes reaching record joint sensitivity. Applications span geodesy, hydrology, volcano monitoring and inertial navigation. He received the CNRS Innovation Medal in 2020.
