Many factors come into play when seeking to find effective quantum controls for exploring fundamental dynamics phenomena as well as technological applications. As finding a control naturally leads to seeking an optimal control, such a search is carried out over a so-called quantum control landscape which is the physical objective as a functional of the control. The topological and non-topological features of such landscapes can greatly influence the performance of the search for an optimal control. The state of understanding about control landscapes will be discussed including examples from simulations and experimental implementations. In this regard, the notion of “easy” refers to efficiently traversing a landscape to locate its optimum, while putting aside often arduous overhead of various types.

Why do effective controls of quantum dynamics appear “easy” to find?
