Outline of Final Research Achievements |
Entangled photon pairs are fundamental resources of the quantum information processing, such as the quantum cryptography, and quantum computing. We have theoretically studied optimal conditions to efficiently generate entangled photon pairs with high quality using semiconductor nanostructures embedded in a microcavity. In particular, we have revealed the optimal conditions for photon-pulse excitation, which enables us to generate entangled photon pairs on demand. We have also proposed semiconductor nano gap structures as a new system to generate entangled photon pairs with high purity.
