Abstract
Rare-earth ions offer a promising platform for the development of quantum repeaters, which will provide the essential links between distant network nodes in a quantum internet. In addition to weakly coupled inner-shell transitions with long optical and spin coherence times, rare-earth ions can also be doped into CMOS-compatible host materials that pair well with established semiconductor foundry processes. In this talk, I will highlight recent progress in coupling rare-earth ions with silicon photonics and discuss some outstanding challenges to be overcome.
Biography
Robert Pettit is the Lead Quantum Scientist at memQ, a Chicago-based startup company focused on developing integrated photonics hardware for quantum networking with rare-earth ions. Prior to joining memQ, he completed his Ph.D. in Optics at the Ï㽶ÊÓƵ in Rochester, NY and was awarded an Intelligence Community Postdoctoral Fellowship at the University of Marlyand in College Park, MD.
