# What Has Quantum Mechanics to do with Factoring? Things I Wish They Had Told Me About Shor's Algorithm

## Main Content

Mueller Lecture Lecture by N. David Mermin Horace White Professor of Physics Emeritus from Cornell University

Quantum computer science will be introduced in the context of its most sensational algorithm: the highly efficient factoring routine discovered by Peter Shor. I will emphasize those features of Shor's procedure that puzzled, surprised, and charmed me in the course of my own efforts to better understand how it does its magic. The subject offers some offbeat glimpses of both quantum mechanics and computation.
