The Free State of Thuringia wants to become an important hub for the German quantum network. With various projects, the state, the federal government and the European Union are driving forward the expansion of a network for quantum communication in Germany. Existing test links for researching quantum-secured fiber links between Erfurt and Jena are now to be extended by new sections in the direction of Nordhausen and, in perspective, Berlin and Frankfurt am Main. A visit by Thuringia's Science Minister Wolfgang Tiefensee to the Fraunhofer Center in Erfurt on August 31, 2023 marked the start of further route expansion, which is being carried out as part of the new Q-net-Q research project.

Researchers from Jena, Berlin, Erlangen-Nuremberg and Wessling have successfully distributed quantum keys between two points using a combination of free-space and fiber links under everyday conditions. On a heterogeneous test bed in Jena, they achieved key rates in the kilobit range per second in daylight. The experiment was implemented as part of the QuNET initiative, a pilot project funded by the German Federal Ministry of Education and Research (BMBF) to develop highly secure communication systems based on quantum technologies.

Bye bye, lens. Hello metasurface! So-called metasurfaces can help to make optical systems thinner in the future, while at the same time increasing their functionality. The problem: Until now, conventional manufacturing processes have often only been able to realize small metasurfaces, often smaller than one square millimeter. Researchers at Fraunhofer IOF have now succeeded for the first time in producing a metasurface with a diameter of almost 30 centimeters using electron beam lithography - a world record. The scientists have now published their method in the "Journal of Micro/Nanopatterning, Materials, and Metrology". Further, the novel metastructure will be on public display for the first time at LASER World of Photonics in Munich, Germany, June 27-30.

How do you decide whether a pedestrian needs to wait or it’s safe for them to cross the road in front of a car? In today’s world, car drivers and pedestrians simply exchange a brief eye contact or small hand gestures to express their in-tentions to one another. But how will future autonomous cars communicate? Researchers involved in the MaMeK project are seeking to answer that ques-tion. They will be presenting their findings at the LASER World of PHOTONICS trade fair in Munich from June 27 to 30 (Booth 415, Hall A2).

Water is becoming increasingly scarce. In the future, innovative satellite technology will ensure that plants are given only as much water as they need, leading to a more sustainable use of this essential resource. A prototype of the technology, LisR, has already been tested on the International Space Station (ISS). A team of researchers from the Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut, EMI, the Fraunhofer Institute for Applied Optics and Precision Engineering IOF and two spin-offs, constellr GmbH and SPACEOPTIX GmbH, has received the Fraunhofer Prize for Human- and Environment-Centered Technology for this development.

Virtual 3D models of real objects, so called »digital twins«, offer numerous advantages – be it for digitization or in the quality control of industrial manufacturing. But the more complex an object, the more difficult it is to measure its shape and transfer it to a 3D model. Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF, in collaboration with MTU Maintenance, have now developed a portable sensor that enables particularly flexible 3D capture, for example of aircraft engines. The handheld scanner, called goSCOUT3D, will be presented to the public for the first time at the OPIE’23 trade fairs in Yokohama from April 19 to 21 and at the CONTROL in Stuttgart from May 9 to 12.

On April 13, the European Space Agency (ESA) will launch its JUICE mission to explore Jupiter and its moons. On board of the spacecraft will be the GALA measuring instrument. It will use laser pulses to measure the surface of the Earth-like moon Ganymede. The instrument was developed by researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF in Jena together with the company HENSOLDT Optronics. GALA will be the first "deep space laser altimeter" to be used at a distance of approximately one billion kilometers from Earth.

Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF have found a new way to produce high-precision components such as mirror optics in a particularly efficient and scalable manner - while maintaining the highest quality and low costs. To achieve this, they are using a new type of production architecture: SWAP-IT. This is being developed as part of the Fraunhofer SWAP lead project with the aim of making industrial manufacturing processes in the factory of the future more flexible, efficient, and economical. At the Hannover Messe from April 17 to 21, the lead project will be presented with its diverse application possibilities in high-precision mirror manufacturing, among other areas.

The future has a color: it is extreme ultraviolet (EUV). With the help of light in this particularly short-wave spectral range, so-called EUV light, it is possible, for example, to produce smaller and more powerful microchips than ever before. But further research faces a problem: Experiments with laser-like EUV light can usually only be conducted at expensive large-scale research facilities. Jena scientist Robert Klas wants to change that. He has developed a compact EUV laser module that can be used to generate this special light much more cost-effectively. Potential applications are possible in semiconductor manufacturing and microscopy. Robert Klas has now been awarded the Hugo Geiger Award for his work.

The European Union is providing 4.3 million euros in funding for a new project to research high-security quantum communication via satellites. In the QUDICE project, an international team of researchers, including members of the Fraunhofer Institute for Applied Optics and Precision Engineering IOF, aims to develop components for space-based distribution of quantum keys. The new hardware is expected to become one day the basis of a European satellite network. At Fraunhofer IOF, a miniaturized source for generating entangled light particles in the telecommunications wavelength range will be built specifically for this purpose. The project has recently started its three-year term.
