  The interplay between two basic quantities -- quantum communication and
information -- is investigated. Quantum communication is an important resource
for quantum states shared by two parties and is directly related to
entanglement. Recently, the amount of local information that can be drawn from
a state has been shown to be closely related to the non-local properties of the
state. Here we consider both formation and extraction processes, and analyze
informational resources as a function of quantum communication. The resulting
diagrams in information space allow us to observe phase-like transitions when
correlations become classical.
