ABSTRACT

In this chapter, we shall collect and generalize the results of the

previous three chapters. We shall come back to the issue of quantum

correlations in terms of information. We shall consider now the

second aspect of quantum information [see Section 11.3], that is,

information selection leading to a local growth of entropy (as it is

the case during ameasurement). This will be the basis for examining

again the whole process of measurement and finally assign an

ontological status to fundamental entities of quantum theory like

states, observables, and properties.
