  Like a silver thread, quantum entanglement [1] runs through the foundations
and breakthrough applications of quantum information theory. It cannot arise
from local operations and classical communication (LOCC) and therefore
represents a more intimate relationship among physical systems than we may
encounter in the classical world. The `nonlocal' character of entanglement
manifests itself through a number of counterintuitive phenomena encompassing
Einstein-Podolsky-Rosen paradox [2,3], steering [4], Bell nonlocality [5] or
negativity of entropy [6,7]. Furthermore, it extends our abilities to process
information. Here, entanglement is used as a resource which needs to be shared
between several parties, eventually placed at remote locations. However
entanglement is not the only manifestation of quantum correlations. Notably,
also separable quantum states can be used as a shared resource for quantum
communication. The experiment presented in this paper highlights the
quantumness of correlations in separable mixed states and the role of classical
information in quantum communication by demonstrating entanglement distribution
using merely a separable ancilla mode.
