Yale Fan: The Universe as a Quantum Computer

WSU Physics Colloquium: 22 January 2026 Yale Fan: The Universe as a Quantum Computer Quantum mechanics is often thought of as the domain of the very small, while gravitation is often thought of as the domain of the very large. This is a false dichotomy. For example, quantum mechanics accounts for the solidity of matter at macroscopic scales via the Pauli exclusion principle and seeds the inhomogeneities in the cosmic microwave background that allow us to probe the large-scale structure of the universe. In this talk, I'll describe how this dichotomy fails dramatically in the opposite direction: classical gravity can function as an oracle for quantum mechanics, suggesting striking results about the dynamics of strongly coupled quantum many-body systems that would be difficult to prove or even conceive of using quantum information theory alone. This two-way flow of insight between gravity and quantum mechanics, which originates from an information-theoretic perspective on the entire universe, suggests new roles for quantum information science in fundamental physics as well as new applications for fundamental physics in quantum information and computation.
