Soutenance de thèse de Soizic HELLO

Soutenance de thèse de Soizic HELLO, doctorante dans le groupe Gaz quantiques du Laboratoire Charles Fabry, le lundi 29 septembre 2025 à 14h00 dans l'auditorium de Thales Research&Technology à Palaiseau, sur le thème : "Compact on-chip cold atom inertial sensor".

Résumé : "The work presented focuses on the development of an inertial sensor based on cold atoms trapped on an atom chip for inertial navigation applications. Based on the principles of atom interferometry, these devices exploit the quantum properties of cold atoms to accurately measure accelerations and rotations. The experimental complexity and bulk of these laboratory experiments pose major obstacles for some embedded applications. In the late 1990s, the possibility of trapping and manipulating atoms on atom chips was demonstrated, enabling a significant reduction in the size of cold atoms sensors as well as their power consumption. This thesis is part of an effort to miniaturize and optimize quantum sensors, aiming to demonstrate the feasibility of a compact architecture. In addition to reducing the size of the sensor, work is being done on miniaturizing the optical system required to prepare the laser beams for the experiments."
