Quantum memories are fundamental devices in quantum information science as they act as interfaces between the photons, used as information carriers, and atoms, exploited for information storage and processing.

Among the possible candidates, the rare earth ion doped crystals are particularly attractive because they are ensembles of ions naturally trapped in inert media. Thanks to their extreme optical coherence, they have a unique potential for future quantum optical technologies.

With the rare earth ion doped materials, we are particularly interested in the development of new telecom-compatible platforms for integrating quantum devices on-chip, with the aim of achieving improved performances due to light confinement over distances exceeding those permitted by the diffraction limit. We work at the intersection of experimental solid-state physics, nanoscience, quantum optics, and quantum information, which gives us unique opportunities to combine fundamental investigation, applied material science, and device engineering for quantum information.
