CRC 787/3: Quantum Networks Based on Single Photons (SP C02)

The project addresses the generation of single photons and photon pairs, as well as their application in quantum information processing. Three objectives have been identified: (1) High-quality single photons are to be generated via resonant excitation of single quantum dots and resonant scattering in the Heitler regime. (2) We will generate time-bin entangled photons from single quantum dots. Stability and versatility of time-bin entanglement will be shown by means of different types of photon conversions. (3) A novel time/frequency protocol for quantum key distribution shall be demonstrated over a 500-m free-space link operated by HHI between two buildings in the city centre.
