Spatial entanglement patterns and Einstein-Podolsky-Rosen steering in a Bose-Einstein condensate
Matteo Fadel, Tilman Zibold, Boris Décamps +1
Many-particle entanglement is a fundamental concept of quantum physics that still presents conceptual challenges. While spin-squeezed and other nonclassical states of atomic ensemb…
Self-testing Dicke states
Matteo Fadel
We show that, upon the observation of a specific measurement statistic, Dicke states can be self-tested. Our work is based on a generalization of the protocol considered by Wu et a…
Bounding the set of classical correlations of a many-body system
Matteo Fadel, Jordi Tura
We present a method to certify the presence of Bell correlations in experimentally observed statistics, and to obtain new Bell inequalities. Our approach is based on relaxing the c…
Mesoscopic quantum superpositions in bimodal Bose-Einstein condensates: decoherence and strategies to counteract it
Krzysztof Pawlowski, Matteo Fadel, Philipp Treutlein +2
We study theoretically the interaction-induced generation of mesoscopic coherent spin state superpositions (small cat states) from an initial coherent spin state in bimodal Bose-Ei…
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…
