Hybrid integrated laser chip for quantum communication


We are happy to announce that the "Computational Optics" group of our Chair for Technology of Optical Systems is participating in another exciting project! On December 01, 2022, the project „Lorelay – Rauscharme Laser für Quantenschlüsselaustausch mit kontinuierlichen Variablen“ was launched.

The project is part of the QuNet initiative of the German Federal Ministry of Education and Research (BMBF). This initiative aims to research high-security communication systems based on quantum technology. The Lorelay project will advance "Continuous-Variable Quantum-Key-Distribution (CV-QKD) systems" for the generation of cryptographic keys based on the use of light and quantum physics. With this technology, a practicable and secure communication will be ensured in a variety of application areas.

In cooperation with the project partners, the task of our chair in this research project is to optimize the required lasers and to ensure compatibility with the CV-QKD systems.

We are looking forward to the upcoming collaboration with the project partners and are excited about the next steps in Lorelay!
