Bipartite entanglement harvesting with multiple detectors
Santeri Salomaa, Esko Keski-Vakkuri, Sergi Nadal-Gisbert
We study bipartite entanglement harvesting from the quantum vacuum of a massless scalar field between two subsystems, each composed of a finite number of Unruh-DeWitt detectors. Us…
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…
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…
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…
