Complex quantum network models from spin clusters

This paper presents a theoretical model for complex quantum communication networks using entangled spin clusters in interacting quantum spin systems as communication links. The authors demonstrate that ground state Greenberger-Horne-Zeilinger (GHZ) clusters from a two-dimensional random transverse-field Ising model can serve as these links, creating networks with complexity comparable to the classical internet. This model provides a framework for further research into the characteristics of the emerging quantum internet.
