My research includes developing and applying mathematical and physical tools to better understand the limitations and utilize the capabilities of information processing resources. I use ideas and results from discrete mathematics, linear and multilinear algebra, information theory, probability theory, the theory of computation, and mathematical/theoretical physics. Current areas of interest include high-significance tests of quantum mechanics, characterization and benchmarks for digital and analog quantum devices, quantum measurement theory, emergence of subsystems in quantum matter and fields, and algebraic quantum information. Most of my work is available at arXiv.org.

A fundamental assumption of quantum information science is that there are degrees of freedom in quantum matter with long-lived coherence suitable for realizing controllable quantum bits--the fundamental information units of quantum information and computation. The existence of such degrees of freedom and the irreducibly quantum features of their states reveals fundamental features of the underlying physics. Thus, quantum information provides a framework for investigating the control and measurement of quantum matter and provides new insights into its states and phases.

Work at the CTQM involving quantum information includes the theory needed to control and characterize trapped ion and atom systems, the use of these systems for ``digital'' and ``analog'' simulations of models of quantum matter beyond the ability of classical simulations, the study of fundamentally quantum correlations and their role in phases of quantum matter, and investigations of the requirements for and properties of emergent and engineered quantum subsystems.
