Combined systems in quantum probability

International Journal of Theoretical Physics Aims and scope Submit manuscript

Abstract

A framework for quantum probability is developed and combinations of systems are studied within this framework. In particular, we consider the horizontal sum, the direct sum, and the Cartesian product of quantum probability systems. The relations between these combinations and the concepts of interference and independence of measurements are derived. We also consider the amplitude superselection structure of these combinations.
