Quantum Science With Rare-Earth Ions In Crystals

Rare-earth ions in crystals, when strongly coupled with optical and superconducting resonators, form a novel platform that facilitates the exploration of quantum many-body physics and the development of light-matter interfaces for the future quantum internet. Through the utilization of a large ensemble of Ytterbium-171 ions doped into a high-cooperativity nanophotonic cavity made of yttrium orthovanadate, we have recently investigated fundamental phenomena in many-body cavity electrodynamics, unveiling a rich interplay between driven inhomogeneous emitters and cavity photons.

Moreover, we have also demonstrated the utility of local nuclear spins within the lattice as deterministic quantum resources, serving as long-lived quantum memory. These advancements not only expand the capabilities of rare-earth ion-based platforms but also open avenues for novel applications in quantum technologies.
