Complex Quantum Network Geometries: Evolution and Phase Transitions [PDF]
Phys. Rev. E 92, 022815 (2015), 2015 Networks are topological and geometric structures used to describe systems as different as the Internet, the brain or the quantum structure of space-time. Here we define complex quantum network geometries, describing the underlying structure of growing simplicial 2-complexes, i.e. simplicial complexes formed by triangles.

Variational Quantum Optimization of Nonlocality in Noisy Quantum Networks [PDF]
, 2022 The inherent noise and complexity of quantum communication networks leads to challenges in designing quantum network protocols using classical methods. To address this issue, we develop a variational quantum optimization framework that simulates quantum networks on quantum hardware and optimizes the network using differential programming techniques. We

Network configuration theory for all networks [PDF]
arXiv, 2021 Entangled quantum networks provide great flexibilities and scalabilities for quantum information processing or quantum Internet. Most of results are focused on the nonlocalities of quantum networks. Our goal in this work is to explore new characterizations of any networks with theory-independent configurations.
