Why Does Controlling Quantum Phenomena Appear Easy to Achieve?

The introduction of optimal control theory and associated optimal control experiments have produced many successful results for manipulating quantum systems including those of high complexity. This paper discusses the reason for this attractive behavior, revealing that the search space landscape for maximizing the probability of making a quantum transition has no false extrema. Although real systems may not be fully controllable, this result provides the basis to explain the generally successful findings from quantum optimal control simulations and experiments, as well as provides a very positive projection of the future for the field.
