Professor Steven Flammia's research interests center around quantum information theory and applications of the theory to a broad range of topics, including condensed matter theory, topologically ordered phases, tensor networks, error correction, quantum optics, precision metrology, and classical statistical inference and machine learning, specifically compressed sensing. He has made important contributions to the study of characterization, verification, and validation of quantum devices.
