  Sharing and receiving information plays a pivotal role in science and
technology. Quantum communication relies on the principles of quantum mechanics
to transmit information in a nonclassical manner. Existing quantum
communication protocols are commonly based on shared entangled states between
sender and receiver, while the transmitting medium is classical. We here
demonstrate that information transfer may be enhanced in a quantum correlated
medium without entanglement distribution. We concretely show that nonclassical
correlations, with nonzero discord, between the first two spins of a spin chain
that acts as a quantum wire can increase the information flow and reduce the
propagation time. We relate this effect to the breaking of the spatial symmetry
of the out-of-time-order correlator that characterizes the spread of
information through the medium.
