Finite-Dimensional State Spaces

  • Louis Marchildon
Part of the Advanced Texts in Physics book series (ADTP)


A mathematical formalism, like the one introduced in Chap. 2, is not by itself a physical theory. The latter includes, in addition, interpretation rules that associate, more or less directly, empirical concepts or procedures to objects of the formalism. The purpose of this chapter is twofold: to state the fundamental interpretation rules of quantum mechanics, and to write down the equation that governs the time evolution of a quantum system. From a logical point of view, interpretation rules and the time-evolution equation are postulates. At first sight, it is not easy to understand their relevance. They are justified through the experimental confirmation of predictions of quantum mechanics, many examples of which will be given in forthcoming chapters.
