Gluing polyhedra with entanglement in loop quantum gravity

Baytaş, Bekir, Bianchi, Eugenio, Yokomizo, Nelson

Understand

In a spin-network basis state, nodes of the graph describe un-entangled quantum regions of space, quantum polyhedra.

  • In this paper we show how entanglement between intertwiner degrees of freedom enforces gluing conditions for neighboring quantum polyhedra.
  • In particular we introduce Bell-network states, entangled states defined via squeezed vacuum techniques.
  • We study correlations of quantum polyhedra in a dipole, a pentagram and a generic graph.
