Research Interests

My main research interests are quantum information and quantum computing. I try to identify the fundamental limits that physics places on communication, information processing, and sensing and understand the implications of these limits both in terms of practical technologies and fundamental physics. This involves finding new ways to think about information and computation, and new ideas for analyzing them.听I have worked on error correction, quantum channel capacities, additivity questions, characterization of quantum annealers, and mathematical properties of entropy.
