The Q & U Bolometric Interferometer for Cosmology, QUBIC, is an innovativeexperiment designed to measure the polarization of the Cosmic Microwave Background andin particular the signature left therein by the inflationary expansion of the Universe. Theexpected signal is extremely faint, thus extreme sensitivity and systematic control are nec-essary in order to attempt this measurement. QUBIC addresses these requirements using aninnovative approach combining the sensitivity of Transition Edge Sensor cryogenic bolome-ters, with the deep control of systematics characteristic of interferometers. This makesQUBIC unique with respect to others classical imagers experiments devoted to the CMBpolarization. In this contribution we report a description of the QUBIC instrument includingrecent achievements and the demonstration of the bolometric interferometry performed inlab. QUBIC will be deployed at the observation site in Alto Chorrillos, in Argentina at theend of 2019.
