The cosmic microwave background (CMB) has been playing a central role in revealing the astonishing secrets of our universe. The biggest attention is currently given to precision measurements of the CMB polarization. The cosmic inflation, which is the leading hypothesis today for the universe before the hot big bang, predicts that gravitational waves that were generated during the inflationary era imprinted a special pattern called the B-mode on the CMB polarization map. Detection of the B-mode signal would allow us …
