Time-optimal control fields for quantum systems with multiple avoided crossings
P. M. Poggi, F. C. Lombardo, D. A. Wisniacki
We study time-optimal protocols for controlling quantum systems which show several avoided level crossings in their energy spectrum. The structure of the spectrum allows us to gene…
Measuring and using non-markovianity
Carlos Pineda, Thomas Gorin, David Davalos +2
We construct measures for the non-Markovianity of quantum evolution with a physically meaningful interpretation. We first provide a general setting in the framework of channel capa…
Enhancement of quantum speed limit time due to cooperative effects in multilevel systems
P. M. Poggi, F. C. Lombardo, D. A. Wisniacki
Deriving minimum evolution times is of paramount importance in quantum mechanics. Bounds on the speed of evolution are given by the so called quantum speed limit (QSL). In this wor…
