Federal Quantum Information Science: An Overview [July 2, 2018]

What makes quantum information science a science? These notes explore the idea that quantum information science may offer a powerful approach to the study of complex quantum systems. We discuss how to quantify complexity in quantum systems, and argue that there are two qualitatively different types of complex quantum system. We also explore ways of understanding complex quantum dynamics by quantifying the strength of a quantum dynamical operation as a physical resource. This is the text for a talk at the ``Sixth International Conference on Quantum Communication, Measurement and Computing'', held at MIT, July 2002.

This Fermi Summer School of Physics on Experimental Quantum Information and Computing represents a primer in an expanding area in physics. In this part, the interest in quantum information (QI) science is due to the discovery that a computer operating on quantum mechanical principles can solve certain important computational problems exponentially faster than any conceivable classical computer. But this interest is also due to the interdisciplinary nature of the field: the rapid growth is attributable, in part, to the stimulating confluence of researchers and ideas from physics, chemistry, mathematics, information theory, and computer science. The lectures cover Quantum Information (QI) processing, spanning quantum optics and laser physics, atomic and molecular physics, physical chemistry, and condensed-matter physics.

I will give an overview of quantum channel discrimination, reviewing the task, its operational significance, connections to other information-theoretic tasks like communication and estimation, and progress in establishing characterizations and bounds on error exponents. Inevitably, quantum effects and additivity issues arise in quantum channel discrimination, revealing fundamental differences between classical and quantum information. Delivered as a talk at "Additivity Problems in Quantum and Classical Information Theory", held at Banff International Research Station during July 12-17, 2026
