Postulates of Quantum Mechanics In this section, we will present six postulates of quantum mechanics. Again, we follow the presentation of McQuarrie [ 1 ], with the exception of postulate 6, which McQuarrie does not include. A few of the postulates have already been discussed in section 3. Postulate 1 . The state of a quantum mechanical system is completely specified by a function that depends on the coordinates of the particle(s) and on time. This function, called the wave function or state function, has the important property that is the probability that the particle lies in the volume element located at at time . The wavefunction must satisfy certain mathematical conditions because of this probabilistic interpretation. For the case of a single particle, the probability of finding it somewhere is 1, so that we have the normalization condition (110) It is customary to also normalize many-particle wavefunctions to 1. 2
