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…
Photon polarization entanglement induced by biexciton: experimental evidence for violation of Bell's inequality
Goro Oohata, Ryosuke Shimizu, Keiichi Edamatsu
We have investigated the polarization entanglement between photon pairs generated from a biexciton in a CuCl single crystal via resonant hyper parametric scattering. The pulses of…
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…
