2    Fundamental commutator and time evolution of state vectors and operators

In the previous chapter we outlined the basic mathematical structure essential for our studies. We are now ready to make contact with physics. This means introducing the fundamental constant images, the Planck constant, which controls the quantum phenomena. Our first step will be to discuss the so-called fundamental commutator, also known as the canonical commutator, which is proportional to images and which essentially dictates how the quantum processes are described. We then examine ...
