Quantum dynamics and control for emerging quantum technologies

Christiane Koch

Quantum advantage refers to exploiting the two essential elements of quantum physics, non-locality and coherence, in modern technologies such as high-precision sensing or large-scale computing. The actual operation of a quantum device requires a unitary operation, and the corresponding time evolution needs to be engineered dynamically. The desired unitaries are implemented by time-dependent external electromagnetic fields. Quantum optimal control theory provides a means to derive the shape of these fields. I will discuss example applications of optimal control theory from quantum sensing and quantum computing and I will show how suitably shaped pulses reach maximum fidelity in minimum time, despite the presence of losses and imprecision.
