Loop Quantum Gravity, spin-foam, gravity and group field theory, share a microscopic picture of space-time geometry described by discrete, pre-geometric degrees of freedom, of combinatorial and algebraic nature. This picture formally translates in a kinematic Hilbert space defined by spin-network states corresponding to a superposition of graphs labelled by group or Lie algebra elements. We study the possibility to reconstruct the geometry of quantum space-time by looking at the correlation structure and entanglement properties of such spin network states, within a quantum informational theoretic setting.
