Professor Goldschmidt's lab studies quantum light-matter interactions with atom-like emitters in solids for applications in quantum information technologies. This includes quantum memory and single photon storage in solid-state rare-earth atom ensembles. In order to take advantage of all the properties of rare-earth materials that make them appealing for such tasks, the research group investigates new materials with higher density of rare-earth atoms to push toward the possibility of long-lived, efficient, solid-state quantum memory. Another project involves coupling rare-earth atoms to resonator structures in order to couple to individual atoms. Such a system will be used as a single photon source and for spin-photon entanglement. Finally, additional projects will focus on generating, characterizing, and using non-classical light for quantum information tasks.
