Entanglement detection in quantum many-body systems using entropic uncertainty relations
Bjarne Bergh, Martin Gärttner
We study experimentally accessible lower bounds on entanglement measures based on entropic uncertainty relations. Experimentally quantifying entanglement is highly desired for appl…

Experimentally accessible bounds on distillable entanglement from entropic uncertainty relations
Bjarne Bergh, Martin Gärttner
Entanglement is not only the resource that fuels many quantum technologies but also plays a key role for some of the most profound open questions of fundamental physics. Experiment…
