<p>Quantum networks are important because of the communication security they offer against classical algorithms attacks and eavesdropping. They are expected to progressively integrate the Internet but they are very different from the technical point of view. After giving some necessary theoretical background, we propose a high-level complex network description of quantum networks that takes into account their specificities. Because there is not a quantum Internet yet, the models cannot be tested against real data yet although network simulators can be used, but are expected to be useful in the future when network data will become available.</p>
