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…
