CMB Polarization as complementary information to anisotropies
J. Kaplan1, J. Delabrouille1, P. Fosalba, C. Rosset1

The origin of CMB polarization is reviewed. Special emphasis is placed on the cosmological information encoded in it: the nature of primordial fluctuations, the connection with the inflation paradigm. Insights into more recent epochs are also discussed: early reionization and high redshift matter distribution from CMB lensing.
