Which Quantum Evolutions Can Be Reversed by Local Unitary Operations? Algebraic Classification and Gradient-Flow-Based Numerical Checks
T. Schulte-Herbrueggen, A. Spoerl
Generalising in the sense of Hahn's spin echo, we completely characterise those unitary propagators of effective multi-qubit interactions that can be inverted solely by {\em local}…

Quantum Gate Design Metric
Navin Khaneja, Bjoern Heitmann, Andreas Spoerl +3
What is the time-optimal way of realizing quantum operations? Here, we show how important instances of this problem can be related to the study of shortest paths on the surface of…
