Elizabeth Goldschmidt, Assistant Professor of Physics at the University of Illinois Urbana-Champaign, will be presenting "Quantum photonics with rare-earth atoms in solids" as part of the Quantum Research Institute's winter seminar series from 11am - noon in the Henderson Room (3rd floor) at the Michigan League. A Zoom option is also provided.

Seminar Description:

Optically active and highly coherent emitters in solids are a promising platform for a wide variety of quantum information applications, particularly quantum memory and other quantum networking tasks. Rare-earth atoms, in addition to having record long coherence times, have the added benefit that they can be hosted in a wide range of solid-state materials. We can thus target particular materials (and choose particular rare-earth species and isotopes) that enable certain application-specific functionalities. I will give an overview of this promising field and discuss several ongoing projects with rare-earth atoms in different host materials and configurations. This includes efforts to identify and grow new materials with rare-earth atoms at stoichiometric concentrations in order to reduce disorder-induced inhomogeneous broadening, as well as photonic integration of rare-earth doped samples to increase the light-atom interaction for practical quantum devices.
