(color online) (a) Scheme of a two-level system driven by a radiation field. (b) Graphs of the theoretical QAZE. The sine-type curves show the evolution of probability P₂ in the non-measurement case with varied |m| = 2,3,5, while the lines with special marks denote P₂ when there are measurements, respectively. Note that the measurements can enhance the transition |1⟩ → |2⟩ to an upper bound of 0.5 (black dashed line).
