QUBIC: Measuring CMB polarization from Argentina

QUBIC (Q and U Bolometric Interferometer for Cosmology) is an ambitious project to measure the polarization of the Cosmic Microwave Background (CMB), which can provide unique information on the very early universe and the cosmic inflation process. The QUBIC instrument combines the extreme sensitivity of cryogenic bolometers and the accurate control of beam-forming and auto-calibration ability of interferometers. The instrument is being finalized and calibrated for a first installation at the Alto Chorrillo high altitude site (Salta province, Argentina) in late 2018, and will produce, in the first two years of operation, a sensitive measurement of CMB polarization, able to detect a tensor to scalar ratio for B-modes 0.01.
