"Rare-earth atoms in solids as a platform for quantum networks "
ABSTRACT:

I will give an overview of the emerging field of rare-earth atoms in solids as the basis for a variety of quantum information applications. These systems have a number of advantageous properties including long inherent coherence times, lack of motional dephasing or substantial spectral diffusion, and high density, that make them promising systems for important quantum information tasks, such as long-lived, efficient photonic quantum memory. A major challenge associated with most atom-like quantum emitters in solids, rare-earth atoms included, is the inhomogeneous broadening of the optical transition energy caused by site-to-site variation in the local environment. I will discuss initial experimental results on the effect of this broadening on electromagnetically induced transparency in a europium doped sample. Finally I will present our plans and ongoing work to mitigate the effects of inhomogeneity by investigating a new class of materials.
