QuNET Initiative at Cyber Security Summit 2023

Quantum key transmission in focus: QuNET initiative presents innovative technologies for secure communication at the Cyber Security Council. Demonstration of quantum key exchange and insight into miniaturized light guides and optics.

On 28 November, the National Cybersecurity Council invited representatives from business, science, politics and civil society to the Cybersecurity Council in Berlin. The QuNET initiative was also on site with an exciting setup for quantum key distribution.

The use of innovative technologies to encrypt data is especially important in the areas of security and defense. To this end, the QuNET initiative is developing highly secure communication systems based on modern quantum technologies.

At the Cyber Security Summit, the QuNET consortium presented a demonstration of a quantum key exchange from one satellite to two ground stations. It was not only possible to learn about quantum state transfer, but also to interact practically with the structure, e.g. by blocking a transmission path. Miniaturized light guides and optics could also be admired through a microscope that showed a transmitter chip for quantum key transmission (QKD).

Third QuNET General Assembly in Jena

QuNET consortia discuss project development and future plans at the third general meeting in Jena. Successful key experiment in ad-hoc hybrid-heterogeneous quantum key transmission networks presented.

The third general meeting of the QuNET/QuNET+ consortia took place in Jena from November 9th to 10th. Representatives of the five core institutes: Fraunhofer IOF; Fraunhofer Heinrich Hertz Institute HHI; German Aerospace Center e.V. DLR; Max Planck Institute for the Physics of Light and FAU Erlangen-Nuremberg as well as employees and researchers of the QuNET+ projects, the Federal Ministry of Education and Research, the VDI e.V./VDE spoke about the project development, initial successes and of course about how the projects will develop in the future.

Matthias Goy, researcher at Fraunhofer IOF, gave a lecture on the first successful key experiment 1 on ad-hoc hybrid-heterogeneous quantum key transmission (QKD) networks in metropolitan areas. Our institute director Andreas Tünnermann also reported on current results from the steering committee and took a first look into the future of the QuNET projects. During the meeting, the next key experiments for 2024 and 2025 were also discussed.

In addition, there were two exciting workshops for the participants. The workshop of the Quantum Communication Germany “SQuaD” project focused on technology transfer and standardization. In a qp-tech.edu training course on the topic of “Introduction to quantum technologies”, the participants dealt with quantum imaging, quantum sensors and metrology. The theoretical impulses were underpinned by practical experiments.

“This was the first face-to-face meeting of this kind for the QuNET initiative. It was therefore impressive to see how closely the individual projects have already grown together and are working towards a common goal,” summarizes Dr. Friederike Fohlmeister (DLR), the third QuNET general meeting.

Towards secure communication of the future

Researchers from Jena, Berlin, Erlangen and Wessling have successfully exchanged quantum keys between two points using a combination of free-space and fiber connections. The experiment was carried out as part of the QuNET initiative, a pilot project funded by the Federal Ministry of Education and Research (BMBF).

Another milestone has been reached on the way to highly secure communication of the future. In a key experiment, the institutes involved – the Max Planck Institute for the Physics of Light, the Friedrich-Alexander University Erlangen-Nuremberg, the DLR Institute of Communications and Navigation as well as the two Fraunhofer Institutes for Applied Optics and Precision Mechanics IOF and the Heinrich Hertz Institute HHI – showed that quantum-secure point-to-point connections can be realized. As part of a key experiment, they established a quantum-secure connection on a test track almost two kilometers long in Jena. They combined transmissions of quantum keys via free-space and fiber connections and achieved transmission rates in the kilobit range per second during the day.

To gain an insight into what was happening, the Federal Ministry of Education and Research (BMBF) and VDI/VDE Innovation Technology visited the experiment in Jena on May 23, 2023. Daniel Behrendt (BMBF), Dirk Ziemann (BMBF), Fabienne Haupert (VDI/VDE) and Kristian Döbrich (VDI/VDE) visited the laboratories and locations of the experiment. The representatives of the individual institutes – Florian Moll (DLR), Ömer Bayraktar (MPL), Nino Walenta (HHI), Anja Milde, Andreas Tünnermann, Thorsten Goebel, Fabian Steinlechner and Matthias Goy (all IOF) – then discussed current and future challenges in the field of data security and quantum communication with the delegation.

Stark-Watzinger: Secure Germany's place at the forefront of quantum technologies

The federal government, together with scientific organizations, is providing three billion euros for future technology.

The Federal Cabinet today approved the quantum technology action plan. It was developed under the leadership of the Federal Ministry of Education and Research (BMBF).

“Quantum technologies are a key technology of the future with enormous potential for our society and economy. Their applications range from the simulation of new drug ingredients to tap-proof communication. With the new action plan, we want to secure Germany’s place at the forefront of quantum technologies and our technological sovereignty. The action plan forms the common political framework and focuses on three fields of action: putting quantum technologies into practice, driving forward technology development in a targeted manner, and creating excellent framework conditions for a strong ecosystem. The Federal Government, together with the scientific organizations, will provide around three billion euros for this purpose.”

Background

The quantum technologies action plan forms the coordinating strategic framework for the Federal Government’s activities in quantum technologies in the years 2023 to 2026. The Federal Government is providing a total of 2.18 billion euros for this purpose. The scientific organizations are contributing 850 million euros. Under the leadership of the Federal Ministry of Education and Research (BMBF), the Federal Ministry for Economic Affairs and Climate Protection (BMWK), the Federal Ministry of Finance (BMF), the Federal Ministry of the Interior and Home Affairs (BMI), the Federal Ministry of Defense (BMVg), the Federal Ministry of Health (BMG) and the Federal Ministry for Digital and Transport (BMDV) contributed to the draft of the action plan.

The cross-departmental concept is divided into three fields of action: The first field of action deals with the development of application-ready products, which will help Germany to take a self-determined path in international competition. The second field of action focuses on targeted technology development. Germany is to become a key player, particularly in the field of quantum computing, and secure future markets by helping to shape standards and norms. The third field of action focuses on promoting a strong ecosystem. The focus here is on founders, networking between science and business, and the creation and expansion of a strong skilled workforce.
