Title: Searching for the primordial CMB B-modes polarization with QUBICAbstract:The Q & U Bolometric Interferometer for Cosmology (QUBIC) is an experiment to measure the primordial B modes polarization of the CMB, that is currently being installed in Alto Chorrillos, in the Province of Salta, Argentina. The detection of the primordial B modes has not been achieved yet, not only because it is an extremely faint signal, but also because of contamination by foregrounds that emit at the same frequencies, most noticeably the galactic thermal dust. In this talk, I will review this novel instrument, its unique architecture, and its strategies to capture this faint signal, which would constitute a unique indirect probe of Inflation.
