The Magic of Combining Coherent Control with Switchable Noise — •Thomas Schulte-Herbrüggen1, Ville Bergholm1,2, and Frank Wilhelm3 — 1Technical University of Munich (TUM) — 2University of Helsinki — 3University of Saarbrücken
Combining coherent control with simplest noise control seems magic: it allows to interconvert arbitrary quantum states no mattter whether they are pure or mixed. We sketch possible experimental implementation in superconducting devices.
We analyse the capabilities of switchable noise in view of the limits between open-loop control and closed-loop feedback control.
All these findings fit nicely in a Lie-geometric picture of dynamic systems control.
