The simplest nontrivial model of the interaction between a two-level atom and a single-mode radiation field is the Jaynes–Cummings model, as follows:

Details
The probability distribution shows both constructive and destructive interference, as well as signal collapses and revivals. These behaviors are purely quantum effects and cannot occur in the semiclassical theory.
Rempe, Walther and Klein [3] have demonstrated collapses and revivals experimentally using a single-atom maser.
