We demonstrate the entangled photon pair generation via biexciton-resonant hyper parametric scattering in CuCl crystal. Quantum tomographic analysis of the polarization correlation measurements showed that the generated photon pairs had a high degree of polarization entanglement, in consequence of J=0 angular momentum of the biexciton state.

We have investigated the quantum statistics of entangled photon pairs generated from biexcitons in CuCl single crystals via resonant hyper-parametric scattering. The generation of multi-photon pairs has been first observed under the high excitation power.

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.
