All core institutes in Berlin united for the start of the SE2 experiments
All five core institutes of the QuNET initiative are on site in Berlin to finalise the last set-ups and preparations for the SE2 experiments. The actual experiments, which will begin on 16 September, represent a significant step in the development of quantum-safe communication networks in Germany.
At the Heinrich Hertz Institute (HHI), Nino Walenta is leading the SE2 experiments. The HHI is applying its expertise in photonic technologies. The Fraunhofer Institute for Applied Optics and Precision Engineering (IOF) contributes to the development of optical systems for quantum communication, which are necessary for high transmission reliability. The DLR Institute of Communications and Navigation is significantly involved in the integration of QKD systems into existing networks, in particular through research in the field of satellite-based quantum communication.
The Max Planck Institute for the Science of Light (MPL) and Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) are working closely together to develop innovative solutions for quantum key distribution (QKD).
Key experiment of the QuNET initiative: Highly secure quantum communication in an urban environment
Starting signal for ground-breaking quantum communication experiment in Berlin
As part of the third large-scale experiment, an urban network with several users in the Berlin metropolitan region will be connected for the first time in a quantum-safe manner via point-to-point connections. The Fraunhofer HHI sites at Einstein- and Salzufer as well as Deutsche Telekom and Bundesdruckerei GmbH will be connected via a 125 km long fibre optic network and additional free beam connections in the air.
A particular focus is on investigating how digital services in the quantum age can be made highly secure through collaboration with Bundesdruckerei GmbH. Sensitive data is exchanged between various institutions in Berlin and protected by quantum cryptography.

Start of the last QuNET+ projects
The kick-off meetings for ICLink, BlueCert and OptiRoute took place at various locations in March
The QuNET+ICLink kick-off meeting took place on 5 March 2024 at the Institute of Solid State Physics at TU Berlin. Participating institutions such as Skyline Photonics GmbH and the Technical Physics Department of Julius-Maximilians-Universität Würzburg came together to present their projects and work packages and to discuss interfaces between the partners. Even though no photos of the event are available, the participation of renowned institutions shows the great interest and commitment to the development of quantum communication systems.
The QuNET+BluCert project started with a successful kickoff on 13 and 14 March at BearingPoint’s German headquarters in Frankfurt am Main. The kickoff included presentations from all partner organisations as well as three different workshops that paved the way for the upcoming challenges in this project. The project focuses on building a certification lab for quantum key distribution (QKD) technology to overcome the certification hurdles and promote the acceptance of this technology.
The QuNET+OptiRoute project was successfully launched on 21 March with a kick-off meeting at the Nokia site in Nuremberg. Michael Bärnreuther, project coordinator, emphasised the importance of highly secure communication with quantum technology. The project focuses on simultaneously routing conventional and quantum signals in fibre optic networks in order to advance quantum communication. Nokia is working with partners such as FAU Erlangen-Nuremberg and the Fraunhofer Heinrich Hertz Institute HHI to tackle the challenges over the next three years.
Specialist group meeting of the QuNET initiative
QuNET develops highly secure communication systems based on the latest quantum technology.
In the first week of March, experts Dr Nino Walenta, Jan Krause, Dr Andy Schreier, Stephanie Renneke, Jerome Wiesemann, Dr Moritz Kleinert, Martin Kresse, Dr Patrick Runge and Pascal Rustige met with 54 participants from industry and research as part of the QuNET initiative, including their 12 QuNET+ projects, in our Science Tech Space showroom.
The discussion on how a QKD network for the secure exchange of information between authorities can be realised was particularly exciting. Important research needs were identified in various working groups and future key experiments were planned.
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.
San Francisco /30 January to 01 February 2024
QuNET initiative at the SPIE Photonics West 2024
The QuNET initiative presented its current systems for secure quantum communication at the largest international trade fair for photonic technologies.
From 30 January to 1 February, SPIE Photonics West, the largest international trade fair for the latest developments in the field of optical and photonic technologies, invited representatives from research and industry to San Francisco. The QuNET initiative was also represented at the trade fair with its current technology systems for secure quantum communication.
The consortium was able to show interested visitors the range of its current research into highly secure communication systems using various exhibits. For example, the transmission of entangled quantum states between a satellite and two ground stations was clearly demonstrated using a model for quantum key transmission (QKD). This illustrated the potential of quantum technologies and the systems developed by the QuNET initiative in the field of practically tap-proof communication.
