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…
Coherent transfer of light polarization to electron spins in a semiconductor
Hideo Kosaka, Hideki Shigyou, Yasuyoshi Mitsumori +5
We demonstrate that the superposition of light polarization states is coherently transferred to electron spins in a semiconductor quantum well. By using time-resolved Kerr rotation…
Negative Polarization through Photon to Electron Spin Polarization Transfer in GaAs Quantum Wells
H. Kosaka, Y. Rikitake, H. Imamura +2
We demonstrate negative polarization created by light-hole exciton excitation in g-factor engineered GaAs quantum wells measured by time-resolved Kerr rotation and polarization-res…
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…
