Abstract = {We show that deterministic quantum computing with a single bit
(DQC1) can determine whether the classical limit of a quantum system
is chaotic or integrable using $O(N)$ physical resources,
where $N$ is the dimension of the Hilbert space of the system under
study. This is a square root improvement over all known classical
procedures. Our study relies strictly on the random matrix
conjecture. We also present numerical results for the nonlinear
kicked top.},
