| Abstract: |
We investigate the possibility that a background independent quantum theory
of gravity is not a theory of quantum geometry. We provide a way for
global spacetime symmetries to emerge from a background independent theory
without geometry. In this, we use a quantum information theoretic
formulation of quantum gravity and the method of noiseless subsystems in
quantum error correction. This is also a method that can extract particles
from a quantum geometric theory such as a spin foam model.
