Tight lower bounds on the time it takes to generate a geometric phase
Niklas Hörnedal, Ole Sönnerborn
Geometric phase is a concept of central importance in virtually every branch of physics. In this paper, we show that the evolution time of a cyclically evolving quantum system is r…

Closed systems refuting quantum-speed-limit hypotheses
Niklas Hörnedal, Ole Sönnerborn
Many quantum speed limits for isolated systems can be generalized to also apply to closed systems. This is, for example, the case with the well-known Mandelstam-Tamm quantum speed…

Margolus-Levitin quantum speed limit for an arbitrary fidelity
Niklas Hörnedal, Ole Sönnerborn
The Mandelstam-Tamm and Margolus-Levitin quantum speed limits are two well-known evolution time estimates for isolated quantum systems. These bounds are usually formulated for full…
