Efficient manipulation of quantum systems via optimal control techniques — •Robert Fisher1, Thomas Schulte-Herbrüggen1, Christof Wunderlich2, Fedor Jelezko3, Jörg Wrachtrup3, and Steffen Glaser1 — 1Department Chemie, Technische Universität München, Germany — 2Fachbereich Physik, Universität Siegen, Germany — 33 Physikalisches Institut, Universität Stuttgart, Germany
We apply optimal control to the design of experiments in quantum information processing. By explicitly accounting for the experimental constraints of addressability and robustness, optimal control techniques allow for the implementation of a broader, more complex class of operations, making new experiments possible. As examples, we consider the implementation of Deutsch and Grover algorithms on two coupled 13C spins at an NV center in diamond, and the preparation of multi-qubit cluster states in a system of trapped ions with a non-ideal coupling topology.
