  Entanglement is unanimously recognized as the key communication resource of
the Quantum Internet. Yet, the possibility of implementing novel network
functionalities by exploiting the marvels of entanglement has been poorly
investigated so far, by mainly restricting the attention to bipartite
entanglement. Conversely, in this paper, we aim at exploiting multipartite
entanglement as inter-network resource. Specifically, we consider the
interconnection of different Quantum Local Area Networks (QLANs), and we show
that multipartite entanglement allows to dynamically generate an inter-QLAN
artificial topology, by means of local operations only, that overcomes the
limitations of the physical QLAN topologies. To this aim, we first design the
multipartite entangled state to be distributed within each QLAN. Then, we show
how such a state can be engineered to: i) interconnect nodes belonging to
different QLANs, and ii) dynamically adapt to different inter-QLAN traffic
patterns. Our contribution aims at providing the network engineering community
with a hands-on guideline towards the concept of artificial topology and
artificial neighborhood.
