Partner-mode overlap as a symplectic-invariant measure of correlations in Gaussian quantum field theories
Ivan Agullo, Eduardo Martín-Martínez, Sergi Nadal-Gisbert +1
We introduce a locally symplectic-invariant quantifier of correlations between arbitrary bosonic Gaussian modes, with particular emphasis on quantum field theory. The quantity, den…
Correlation and Entanglement partners in Gaussian systems
Ivan Agullo, Eduardo Martín-Martínez, Sergi Nadal-Gisbert +2
We introduce a framework to identify where the total correlations and entanglement with a chosen degree of freedom reside within the rest of a system, in the context of bosonic man…
Entanglement and correlations between local observables in de Sitter spacetime
Patricia Ribes-Metidieri, Ivan Agullo, Béatrice Bonga
Studies of quantum field entanglement in de Sitter space based on the von Neumann entropy of local patches have concluded that curvature enhances entanglement between regions and t…
The multimode nature of spacetime entanglement in QFT
Ivan Agullo, Béatrice Bonga, Eduardo Martín-Martínez +5
We demonstrate the presence of multimode entanglement in the vacuum state of a free, massless scalar quantum field in four-dimensional flat spacetime between two sets of field mode…
Inflation does not create entanglement in local observables
Patricia Ribes-Metidieri, Ivan Agullo, Béatrice Bonga
Using modern tools of relativistic quantum information, we compare entanglement of a free, massive scalar field in the Bunch-Davies vacuum in the cosmological patch of de Sitter sp…
