Occitan researchers and engineers are present in the field of quantum technologies. The Occitanie laboratories have in particular a renowned expertise in new solid-state supports for quantum information but also the nano- and micro-fabrication of derived quantum components. The fields of application that they explore, both in their theoretical and experimental aspects, relate to (i) quantum communications (solid-state sources of quantum light, quantum interfaces, cryptography protocols, quantum logic, deployment of quantum communications in space, etc.), (ii) quantum sensors (for magnetometry, electrometry, thermometry, force measurement, gravity measurement, etc.) as well as (iii) quantum simulation (by use of collective states in atomic assemblies or semiconductor materials, etc. ).
