Ryōsuke Shimizu, T. Yamaguchi, Yasuyoshi Mitsumori, Hideo Kosaka, Keiichi Edamatsu · 2007
We propose and demonstrate a novel scheme for the generation of polarization entanglement from spatially correlated photon pairs generated by parametric down-conversion. Using the state, we also demonstrate the violation of Bell's inequality.
