Title: "Quantum networking with solid-state atom-like emitters."

Speaker: Elizabeth Goldschmidt, Assistant Professor, Department of Physics, The Grainger College of Engineering, University of Illinois Urbana Champaign.

Optically active and highly coherent atom-like emitters in solids are a promising platform for a wide variety of exciting quantum information applications. They are particularly well-suited as the building blocks of quantum networks, acting as light-matter interfaces that transduce quantum information back and forth between stationary matter-based qubits and optical "flying qubits" in order to transmit quantum information over distances that range from a few mm to thousands of km. Dr. Goldschmidt will give an overview of this broad field and then discuss my work with a particular class of solid-state emitters, rare-earth atoms in solids, whose record-long coherence times and compatibility with a wide range of host materials make them extremely promising.  She will discuss some ongoing projects, including her efforts to identify and grow new materials with rare-earth atoms at stoichiometric concentrations in order to reduce the disorder-induced inhomogeneous broadening and our work investigating nanophotonic integration of rare-earth doped samples that aims to increase the light-atom interaction in order to make practical quantum devices.
