中文摘要Entangled states are key resource for quantum information processing. In linear optics quantum computing,the most widely used entanglement resource is polarization entangled photon pairs generated via type-II spontaneous parametric down-conversion. However, the brightness is not. sufficient to perform quantum communication experiment between ground and satellite. In this paper we have developed a high-brightness entangled resource based on periodic polarization and quasi-phase marched periodically poled KTiOPO4 crystal. The number of generated entangled pairs is about 1.6 x 10(4) s(-1) mW(-1) and the visibility is 27:1. Our source is with about one order of magnitude brighter than previous sources based on P-barium borate crystal. This leads to an immediate possibility for applications in the field of quantum key distribution, quantum teleportation and quantum computation. Particularly it would form a solid basis for future global quantum network.
