Quantum Photonics
Quantum Photonics includes the generation, emission, transmission, switching, amplification and, in general, covers the engineering and coherent control of quantum systems, i.e. down to the single photon level. It is a key enabling quantum technology, both for current device and system development in QKD, as well as future entangled quantum network applications.
On the applied side, we are exploiting a range of Integrated photonic technologies aimed at miniaturisation, compactness and scalability for QKD. On the more fundamental side, we are constantly exploring and developing novel approaches, exploiting classical, quantum and nonlinear optics, that allow us to produce single-, pair-, and multi-photon sources, with well defined and reproducible characteristics.
Our primary goals are to investigate and engineer:
- Next generation photon sources
- Single photon frequency conversion interfaces
- Quantum-capable photonic integrated chips
A SiN reciever (Bob) chip for 2.5GHz-rate QKD system.
