Title  Holographic entanglement entropy from random tensor networks via group field theory 
Abstract  We investigate the use of tensor networks techniques and quantum information theory for the study of the entanglement properties of quantum geometry states. In the language of the group field theory, we describe spin network states as quantum manybody systems. The very connectivity of such states, encoded in the links of the underlying graphs, is associated with the entanglement between the fundamental quanta constituting them. We establish a dictionary between group field theory states and (generalised) random tensor networks. With such a dictionary at hand, we target the calculation of the RyuTakayanagi formula for the entanglement entropy in the quantum gravity formalism of group field theory.
