Generation of polarization entanglement from spatially-correlated photons in spontaneous parametric down-conversion
Ryosuke Shimizu, Takashi Yamaguchi, Yasuyoshi Mitsumori +2
We propose a novel scheme to generate polarization entanglement from spatially-correlated photon pairs. We experimentally realized a scheme by means of a spatial correlation effect…
Quantum diffraction and interference of spatially correlated photon pairs and its Fourier-optical analysis
Ryosuke Shimizu, Keiichi Edamatsu, Tadashi Itoh
We present one- and two-photon diffraction and interference experiments involving parametric down-converted photon pairs. By controlling the divergence of the pump beam in parametr…
Quantum diffraction and interference of spatially correlated photon pairs generated by spontaneous parametric down-conversion
Ryosuke Shimizu, Keiichi Edamatsu, Tadashi Itoh
We demonstrate one- and two-photon diffraction and interference experiments utilizing parametric down-converted photon pairs (biphotons) and a transmission grating. With two-photon…
