Description
Quantum spin networks are a phenomenal quantitative tool to investigate the operational content of the gravitational field at the quantum scale. In this light, spin network entanglement has recently become a central resource to characterize dynamical signatures and holographic behaviour of quantum spacetime geometry, providing a new tool to study the emergence of classical spacetime geometry from its quantum description. We review a series of recent results focusing on the notion of random spin network intended as a proxy of a complex quantum many-body description of quantum geometry concerning the emergence of holographic behaviour in a regime of quantum typicality. For such states, we discuss the notion of quantum negativity as a good witness of multipartite entanglement in an open-quantum state description of bounded 3D-space regions.
