In order to become familiar with the basic concepts of density matrix theory we will begin by considering the problem of describing the spin states of spin-1/2 particles. First of all we will review some results of the quantum mechanical theory of experiments with Stern–Gerlach magnets and then in the following sections we will reinterpret the results and discuss them in more detail.
