Description
B-modes in cosmic microwave background (CMB) polarization is smoking gun signature of inflationary universe. Inflationary universe predicts primordial gravitational waves, the primordial gravitational waves created degree-scale odd-parity components in CMB polarization pattern: B-modes. Therefore, the primary goal of CMB polarization studies in the next decade is detection of B-modes.
Many experiments are aiming to observe B-modes. It is very exciting period. I will review experimental approach with mainly focusing on QUIET experiment. Limits to date and future prospects will be also discussed from the experimental view points.
