Our research focuses on the development of light-matter quantum interfaces that enable quantum communication over extended networks as well as quantum information processing within and across network nodes. This involves studying cavity-enhanced interaction between photons and rare-earth ions (both individual and ensembes) with the goal to create single and entangled photons, quantum memories for light, as well as quantum computing nodes.
