Direct calculation of mutual information of distant regions
Abstract We consider the (Rényi) mutual information, I n A B = S A n + S B n − S A ∪ B n $$ {I}^{(n)}\left(A,B\right)={S}_A^{(n)}+{S}_B^{(n)}-{S}_{A\cup B}^{(n)} $$ , of distant compact spatial regions A and B in the vacuum state of a free scalar field. The distance r between A and B is much greater...
