Our group has worked on theoretical analyses and experimental demonstrations of both measurement-based and coherent-feedback quantum control. We currently focus on exploring the utility of coherent feedback for synthesizing new functional behaviors for attojoule/quantum nanophotonics, and on understanding feedback as computation in all-optical information processing architectures (including both quantum computers and Coherent Ising Machines).
