Secure communication networks using integrated quantum light sources

In the framework of the project QuSecure quantum communication systems will be developed based on semiconductor quantum light sources.

For this purpose the full potential of single-photon sources based on semiconductor quantum dots will be exploited. Different protocolls for quantum key distribution will be implemented, taking advantage of the scalability of state-of-the-art quantum light sources as well as the specific quantum-mechanical properties of the generated light states.

Aiming at the implementation of quantum communication scenarios immune against eavesdropping attacks at GHz clock rates, QuSecure will essentially improve the security level and key rates compared to the current state-of-the-art. Overarching project goal is to establish an urban quantum communication network based on quantum light sources.

This QuSecure-Network will be located at the Campus of Technische Universität Berlin, right at the heart of the German capital.

The project QuSecure (contract number: 13N14876) is funded by the German Federal Ministry of Education and Research (BMBF) within the funding program Photonic Research Germany.
