Loop quantum gravity and the CMB: toward pre-big bounce cosmology
A. Barrau1

The loop approach to quantum gravity is the most promising way to derive a background-independent quantization of general relativity. Interestingly, it was shown in the last years that cosmological observations -in particular with tensor modes in the primordial spectrum- could open a new window to observationally probe quantum gravity. I will briefly review the current situation and, assuming a standard evolution for the background, underline the missing links to build a fully consistent framework.
