Research output: Contribution to journalConference articlepeer-review


We demonstrate the first experimental realization of the entangled photon pair generation via biexciton-resonant hyper parametric scattering in CuCl crystal. Polarization correlation measurements and quantum tomographic analysis shows that the generated photon pairs have high degrees of polarization entanglement.
