  In this paper we describe QUBIC, an experiment that takes up the challenge
posed by the detection of primordial gravitational waves with a novel approach,
that combines the sensitivity of state-of-the art bolometric detectors with the
systematic effects control typical of interferometers. The so-called
"self-calibration" is a technique deeply rooted in the interferometric nature
of the instrument and allows us to clean the measured data from instrumental
effects. The first module of QUBIC is a dual band instrument (150 GHz and 220
GHz) that will be deployed in Argentina during the Fall 2018.
