Cristaux et dynamique des états quantiques

Activité scientifique

We design, grow, and characterize rare earth doped crystals and color centers in diamond in which we aim at controlling optical and spin non-classical states. These materials, produced in the form of bulk and nanostructured single crystals, show extremely long-lived quantum states at low temperature. This unique property in the solid state enables us to address a broad range of applications, from quantum information processing and communication, to spectral analysis and medical imaging.
