GENERATION OF ENTANGLED PHOTONS IN A SEMICONDUCTOR AND VIOLATION OF BELL'S INEQUALITY

摘要

We demonstrate the generation of entangled photon pairs via biexciton-resonant hyper parametricscattering in CuCl crystal. Quantum state tomography show that the generated photon pairs have a high degree of polarization entanglement. Also we show that the photon pairs violate Clauser-Horne-Shimony-Holt type Bell's inequality.
