  In this note we discuss a topological realization of the quantum
teleportation protocol. Such a realization facilitates keeping track of the
evolution of quantum correlations in the system. It is then suggested, that an
implementation of a similar protocol can serve as a toy model of a process of
information transfer between causally disconnected regions, such as the one
that should take place in a unitary evolution of a quantum black hole. Hawking
quanta provide the necessary entangled pairs for the teleportation channel, and
the same interaction mechanism that creates the Hawking pairs, destroys the
entanglement at the late stages of the evolution. Different steps of the
teleportation protocol are characterized by the entropies associated with the
disconnected regions, and one can introduce an analog of the Page curve for the
entropy of the Hawking radiation. Some regions of the ``black hole'' interior
appear to actually encode the information of the exterior, so it is natural to
identify them with the ``islands'' of the semiclassical gravity analysis.
