Abstract:
We show that deterministic quantum computing with a single bit can determine whether the classical limit of a quantum system is chaotic or integrable using [Formula Presented] 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. © 2003 The American Physical Society.

- It is important to note that (Formula presented) need not increase with N; in fact, it is quite the opposite. The probability of error scales like the overlap of two Gaussian distributions of width (Formula presented) and centered about points (Formula presented) and (Formula presented) clearly, this overlap decreases with N
