Query: Quantum sensitive dependence   Wave functions of bounded quantum systems with time-independent potentials,
being almost periodic functions, cannot have time asymptotics as in classical
chaos. However, bounded quantum systems with time-dependent interactions, as
used in quantum control, may have continuous spectrum and the rate of growth of
observables is an issue of both theoretical and practical concern. Rates of
growth in quantum mechanics are discussed by constructing quantities with the
same physical meaning as those involved in the classical Lyapunov exponent. A
generalized notion of quantum sensitive dependence is introduced and the
mathematical structure of the operator matrix elements that correspond to
different types of growth is characterized.
