Device-independent characterization of quantum instruments
Sebastian Wagner, Jean-Daniel Bancal, Nicolas Sangouard +1
Among certification techniques, those based on the violation of Bell inequalities are appealing because they do not require assumptions on the underlying Hilbert space dimension an…
Certifying the building blocks of quantum computers from Bell's theorem
Pavel Sekatski, Jean-Daniel Bancal, Sebastian Wagner +1
The power of quantum computers relies on the capability of their components to maintain faithfully and process accurately quantum information. Since this property eludes classical…
Bell correlations in a many-body system with finite statistics
Sebastian Wagner, Roman Schmied, Matteo Fadel +3
A recent experiment reported the first violation of a Bell correlation witness in a many-body system [Science 352, 441 (2016)]. Following discussions in this paper, we address here…
