Optimal witnessing of the quantum Fisher information with few measurements
Iagoba Apellaniz, Matthias Kleinmann, Otfried Gühne +1
We show how to verify the metrological usefulness of quantum states based on the expectation values of an arbitrarily chosen set of observables. In particular, we estimate the quan…

Thermodynamical cost of some interpretations of quantum theory
Adán Cabello, Mile Gu, Otfried Gühne +2
The interpretation of quantum theory is one of the longest-standing debates in physics. Type I interpretations see quantum probabilities as determined by intrinsic properties of th…

Characterizing the width of entanglement
Sabine Wölk, Otfried Gühne
We introduce the concept of entanglement width as measure of the spatial distribution of entanglement in multiparticle systems. We develop criteria to detect the width of entanglem…
