  The Einstein-Podolsky-Rosen paradox (1935) is reexamined in the light of
Shannon's information theory (1948). The EPR argument did not take into account
that the observers' information was localized, like any other physical object.
General relativity introduces new problems: there are horizons which act as
one-way membranes for the propagation of quantum information, in particular
black holes which act like sinks.
