Closed loop optimal control on NV centers in diamond — •Florian Frank1, Thomas Unden1, Jorge Casanova2, Zhenyu Wang2, Ressa Said3, Jonathan Zoller3, Martin Plenio2, and Fedor Jelezko11Institute for Quantum Optics, Ulm University, Ulm, Germany — 2Institute of Theoretical Physics, Ulm University, Ulm, Germany — 3Institute for Complex Quantum-systems, Ulm University, Ulm, Germany

The objective of optimal control is to control a given system in a way that its output matches a reference. In closed loop optimal control, the controler gets an active feed back of the experiment to tune the control parameters . We use this technique to optmize the fidelity of quantum operations on the nitrogen vacancy center. Therefore we tune the microwave pulses and sequences to maximize the fidelity of this operations.
