Abstract
Rare-earth ions in solids at cryogenic temperatures are a promising candidate for quantum memory devices due to their long-lived coherence properties. In currently available europium-doped materials, site-to-site variations of the energy levels cause inhomogeneous broadening that prevents resolution of long-lived spin states. These spin states can be resolved with spectral hole burning techniques at the expense of limiting the memory bandwidth and efficiency and by lowering the optical depth. A stoichiometric material has previously demonstrated sufficiently narrow linewidths without sacrificing optical depth. Here we present progress on europium stoichiometric materials as candidates for quantum memory applications.
