IAP 2004 Activity

Exploring Quantum Chaos with Quantum Computers
David Poulin & Joseph Emerson Perimeter Institute, Canada
No enrollment limit, no advance sign up
Participants welcome at individual sessions (series)
Prereq: Linear algebra + two years of physics

We discuss how quantum information processors could be used to study various aspects of quantum chaos. In particular, we will show how the ability to simulate the dynamics of certain quantum systems on a quantum computer enables us to evaluate interesting physical quantities, such as spectral correlation functions and stability under perturbation, which serve as signatures of quantum chaos. Time permitting, we will also discuss the problem of the emergence of classical chaos from quantum theory.
