TL;DR: An excess of B-mode power over the base lensed-ΛCDM expectation is found in the range 30 < ℓ < 150, inconsistent with the null hypothesis at a significance of >5σ, and it is shown that systematic contamination is much smaller than the observed excess.

TL;DR: An analysis of all data taken by the BICEP2 and Keck Array cosmic microwave background (CMB) polarization experiments up to and including the 2014 observing season yields an upper limit r_{0.05}<0.09 at 95% confidence, which is robust to variations explored in analysis and priors.

TL;DR: For example, a future CMB and large-scale structure (LSS) experiments are poised to test the leading paradigm for these earliest moments and to detect the imprints of the inflationary epoch, thereby dramatically increasing our understanding of fundamental physics and the early universe.

TL;DR: The Q/U Imaging ExperimenT (QUIET) as discussed by the authors employs coherent receivers at 43 GHz and 94 GHz, operating on the Chajnantor plateau in the Atacama Desert in Chile, to measure the anisotropic in the polarization of the cosmic microwave background (CMB).
