Published in a special issue of the "Journal of Cosmology and Astroparticle Physics" eight articles of the QUBIC collaboration that describe in detail the current configuration of the experiment and the results of the calibrations.

QUBIC (Q&U Bolometric Interferometer for Cosmology) is an experiment designed to study the physics of the newborn universe, a moment after the Big Bang. It will do this by observing the Cosmic Microwave Background, the first light in the universe, in particular by measuring one of its polarized components, the so-called B-modes.

QUBIC is a completely new concept telescope, based on a technique called “bolometric interferometry”. It will observe the sky starting from the end of 2022, from a high altitude (5000 m) desert site in Argentina, near the San Antonio de Los Cobres locality. After its development and integration in European laboratories, the instrument arrived in Argentina in the city of Salta in July 2021. Preliminary tests have confirmed that after transport and the new installation the instrument is performing as expected. The final phase of laboratory tests will be held in the Argentine experimental site.

This preparatory phase is a fundamental step that leads to the actual phase of taking the data of cosmological interest which, specifically, will begin at the end of this year.
