  QUBIC is a unique instrument that crosses the barriers between classical
imaging architectures and interferometry taking advantage from both for high
sensitivity and systematics mitigation. The scientific target is the detection
of the primordial gravitational waves imprint on the Cosmic Microwave
Background which are the proof of inflation, holy grail of modern cosmology. In
this paper, we show the latest advances in the development of the architecture
and the sub-systems of the first module of this instrument to be deployed in
Dome Charlie Concordia base - Antarctica in 2015.
