The forum for quantum communication in Germany

At the ‘Forum for Quantum Communication in Germany’ on 17.10.24 at the Fraunhofer HHI, State Secretary Dr Roland Philippi emphasised the central role of research funding by the BMBF. This is crucial for strengthening IT security and technological sovereignty. The event was organised by the BMBF-funded networks QR.X, QuNET and SQuaD and brought together leading representatives from research, industry and start-ups. The aim was to highlight prospects for quantum communication in Germany and present concrete progress.

The QuNET initiative demonstrated quantum-secured data transmission in Berlin’s inner-city network, a possible approach for the secure transmission of personal data in digital government services. QR.X presented quantum teleportation as a technological cornerstone for future quantum networks. The SQuaD umbrella project provided information about its support for technology transfer and the development of an innovation ecosystem for quantum communication in Germany. The forum’s selected discussion topics included research & development, transfer & value creation, data sovereignty, IT security research, training & careers and EU & international perspectives. Research projects and industry from the field of quantum communication were presented at kiosks.

In order to promote exchange within the forum and to honour the BMBF’s pioneering funding strategy, an impulse paper on the topic of quantum communication was drawn up from the midst of the research and industry ecosystem in the run-up to the forum and ceremoniously presented to the BMBF State Secretary Dr Roland Philippi at the event.

QuNET-Initiative beim Besuch des deutschen Bundespräsidenten

Fraunhofer IOF presents quantum key distribution model to the Federal President as part of the QuNET initiative for highly secure communication systems and emphasises the pioneering role of quantum research in global communication systems.

The QuNET initiative, which is funded by the Federal Ministry of Education and Research, is developing the foundations for highly secure quantum communication systems using state-of-the-art quantum technology. The systems for practically tap-proof communication can thus pave the way for long-term data security and technological sovereignty.

On the occasion of the Federal President’s visit to Fraunhofer IOF last week, QuNET researchers presented a model for quantum key distribution (QKD). It demonstrated the exchange of quantum keys between a satellite and two ground stations. Such a system could one day form the basis for a global quantum network.

Frank-Walter Steinmeier was able to experience the exhibit and the research behind it up close and observe how interference signals can be detected by changing the quantum states.

Fraunhofer IOF is also researching the future of communication with quanta in other projects such as HYPERSPACE, thus emphasising the importance of quantum research in the field of global communication systems.
