Nelson lecture on Friday March 15th

HH-305 from 3:30-4:30pm

Here are the details:

This is the 2023-24 Nelson lecture held annually in honour of our former colleague Evelyn Nelson.

**Speaker:** Henry Yuen, Columbia University

**Title:** A Tale of Turing Machines, Quantum Entanglement, and Operator Algebras

See previous Nelson lectures here

**Abstract:** In a recent result known as “MIP* = RE,” ideas from three disparate fields of study — computational complexity theory, quantum information, and operator algebras — have come

together to simultaneously resolve long-standing open problems in each field, including a 45- year old mystery in mathematics known as Connes’ Embedding Problem. In this talk, I will

describe the evolution and convergence of ideas behind MIP* = RE: it starts with three landmark discoveries from the 1930s (Turing’s notion of a universal computing machine, the phenomenon of quantum entanglement, and von Neumann’s theory of operators), and ends with some of the most cutting-edge developments from theoretical computer science and quantum computing. This talk is aimed at a general scientific audience, and will not assume any specialized background in complexity theory, quantum physics, or operator algebras.

Bio: Henry Yuen is an Associate Professor of Computer Science at Columbia University. His research focuses on the interplay between quantum computing, complexity theory, cryptography, and information theory. Yuen received a BA in mathematics from the University of Southern California in 2010, and received his PhD in computer science at MIT in 2016. He is a recipient of the NSF CAREER award and a Sloan Fellowship.
