__TITLE:__Optimal Control for Entangling Quantum Gates

__ABSTRACT:__ Numerical optimal control techniques are a powerful tool in the design
of quantum technology, allowing to determine fundamental limits in
steering a quantum system. In the context of entangling two-qubit
quantum gates, I will give an overview of the most important numerical
techniques, and discuss strenghths and weaknesses of several
gradient-free and gradient based optimization methods. I will also show
how optimal control can be employed to address the sensitivity of
quantum system to classical and quantum noise.
