The Quantum Labyrinth

This volume deals with the question of whether quantum mechanics can provide a picture of physical reality. This question is investigated from physical, philosophical, and logical perspectives on the basis of modern views on measurement and open quantum systems. New ways are found of respecting the rules of classical logic in quantum mechanics, by developing a formalization of the concept of a `context' within a modularized version of modal logic. Various applications are given, both within and outside quantum theory. A `contextual quantum process theory' is presented as a general framework for further interpretation. Several such interpretations are outlined, and ensuing problems of completeness and (non)locality are discussed. A special chapter is devoted to a manifestly covariant relativistic interpretation in terms of `quantum events'. This book will be of interest to experts on quantum theory, but it will also appeal to a wider public of physicists, philosophers and logicians.
