Presentations by partners

• Presentation of AtomQtrl by Johan Boullet (Naquidis Center)

• Presentation of ReNaPack by Hugues Granier (LAAS)

• Electromagnetic field sensors using hot and cold Rydberg atoms, CARAMELS project under the PEPR Quantum, presented via video conference by Sylvain Schwartz, research director at ONERA, and Fabien Bretenaker, CNRS research director at Lumière, Matière et Interfaces (LuMIn)

• Pharao/ACES mission by François-Xavier Esnault (CNES)

A poster session was also held at the end of the first day to highlight the younger generations’ involvement in the project. Participants also had the opportunity to tour the LCAR and observe demonstrations of the work being conducted there as part of the QAFCA project.
