This is a mathematical physics talk by Jan Mandrysch (IQOQI Wien) on the relative entropy of multi-mode squeezed states of a free scalar quantum field in Minkowski spacetime. The main result is that squeezing local in space yields physically unreasonable states with divergent energy density and relative entropy, whereas squeezing local in spacetime produces physically reasonable states with finite
