Operational Quantum Physics (2nd Corr Print ed.)

This text offers a systematic presentation of quantum mechanics, making use of the full probabilistic structure of this theory.

Accordingly, the notion of an observable as a positive operator valued (POV) measure is explained in great detail, and the ensuing quantum measurement theory is developed and applied both to a resolution of long-standing conceptual and interpretational puzzles in the foundations of quantum mechanics, and to an analysis of various recent fundamental experiments.
