Monogamy and backflow of mutual information in non-Markovian thermal baths

ACS Costa, RM Angelo, MW Beims - Physical Review A, 2014 - APS
We investigate the dynamics of information among the parties of tripartite systems. We start
by proving two results concerning the monogamy of mutual information. The first one states …
