Local Vacuum Entanglement through Most Entangled Modes
T. Rick Perche, Patricia Ribes-Metidieri
We find the shape of the modes containing most of the entanglement between two disjoint spherical regions in the vacuum of a free massless real scalar field in 1+3 Minkowski spacet…
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…
How ubiquitous is entanglement in quantum field theory?
Ivan Agullo, Béatrice Bonga, Patricia Ribes-Metidieri +2
It is well known that entanglement is widespread in quantum field theory, in the following sense: every Reeh-Schlieder state contains entanglement between any two spatially separat…
Does inflation squeeze cosmological perturbations?
Ivan Agullo, Béatrice Bonga, Patricia Ribes Metidieri
There seems to exist agreement about the fact that inflation squeezes the quantum state of cosmological perturbations and entangles modes with wavenumbers and . P…
