Quantum Optimal Control in Action. I: Overview — •Thomas Schulte-Herbrüggen1, Shai Machnes2, and Ville Bergholm1 — 1TU-Munich, Dept. Chem. — 2University of Ulm, Inst. Theor. Phys.
For implementing high-precision quantum simulation and quantum computation in given experimental set-ups, optimal control tools are establishing themselves as indispensable.
Starting from practical examples of control problems (as in superconducting solid-state devices, cavity qed), we elucidate the unified framework of bilinear control systems underlying the matlab-based quantum optimal-control platform dynamo . It provides optimised steerings to all the typical control problems such as state transfer and synthesis of unitary gates or of quantum maps  in closed and open Markovian or non-Markovian systems.
We sketch a plethora of applications reaching from Josephson elements, spins in quantum dots to ion traps etc.
Finally, we point out features of state-of-the-art algorithms implemented .
