Coupling of Random Systems
David Lanzenberger and Ueli Maurer
Abstract
This paper makes three contributions. First, we present a simple theory of
random systems. The main idea is to think of a probabilistic system as an
equivalence class of distributions over deterministic systems. Second, we
demonstrate how in this new theory, the optimal
information-theoretic distinguishing advantage between two systems can be
characterized merely in terms of the statistical distance of probability
distributions, providing a more elementary understanding of the distance of
systems. In particular, two systems that are
