Abstract
It is argued that dynamical chaos in quantum mechanics arises solely from the collapse rule applied in measurements. As such it is quite distinct from classical (deterministic) chaos, which arises from the dynamical law itself. It is shown, however, that if the particles of a quantum system are regarded as “real,” i.e., if their positions are made part of the state description, one obtains a formulation of quantum theory, Bohmian mechanics, in which “quantum chaos” also arises solely from the dynamical law. Moreover, this occurs in a manner far simpler than in the classical case.
