Does a large quantum Fisher information imply Bell correlations?
Florian Fröwis, Matteo Fadel, Philipp Treutlein +2
The quantum Fisher information (QFI) of certain multipartite entangled quantum states is larger than what is reachable by separable states, providing a metrological advantage. Are…
Split spin-squeezed Bose-Einstein Condensates
Yumang Jing, Matteo Fadel, Valentin Ivannikov +1
We investigate and model the behaviour of split spin-squeezed Bose-Einstein condensates (BECs) system. In such a system, a spin-polarized BEC is first squeezed using a …
Bell correlations at finite temperature
Matteo Fadel, Jordi Tura
We show that spin systems with infinite-range interactions can violate at thermal equilibrium a multipartite Bell inequality, up to a finite critical temperature . Our framewo…
Bell correlations depth in many-body systems
Flavio Baccari, Jordi Tura, Matteo Fadel +6
While the interest in multipartite nonlocality has grown in recent years, its existence in large quantum systems is difficult to confirm experimentally. This is mostly due to the i…
