Quantum communication protects data transmission in an encrypted way that no longer leaves eavesdropping attempts undetected. As part of the European Quantum Flagship initiative, Fraunhofer HHI is developing novel optical integration solutions that make such technologies affordable for everyone. Within the UNIQORN project, Fraunhofer HHI paves the way for the use of quantum technologies in the mass market together with 16 international partners.
The hybrid photonic integration platform PolyBoard, developed at Fraunhofer HHI, enables the flexible and efficient combination of various optical functionalities on a single chip. This toolbox will be further developed in the coming years as part of the "Quantum Flagship" of the European Union to meet the specific requirements of novel quantum technologies.
The project UNIQORN (Affordable Quantum Communication for Everyone: Revolutionizing the Quantum Ecosystem from Fabrication to Application) has set itself the goal of miniaturizing quantum technologies using photonic integration and making them available to users as system-on-chip solutions.
The project will develop the key components for the quantum communications systems of the future. They are used, among other things, to generate true random numbers and to secure key distribution and include specialized quantum optical sources and detectors. An important focus of the research is on integrated system-on-chip solutions. They are the basis for highly miniaturized optical systems that can fully exploit quantum mechanical properties such as entanglement and squeezed light.
The core of this integration is the micro-optical bench technology of the PolyBoard platform, which makes it possible to combine large, millimeter size, optical components such as crystals for generating entangled photons with typically sub-millimeter sized integrated optical components and functionalities on a PolyBoard chip. It is based on the generation of free-space optical areas inside photonic integrated chips with the help of specially adapted lenses.
As a result, known material systems for quantum technology can be combined directly with photonic integrated circuits, without having to compromise on the performance of the micro-optical components. So far, this technology facilitated the development of miniaturized optical components for telecom and datacom applications as well as micro-optical chips for analytics and sensor technology.
In the UNIQORN consortium, which is coordinated by the AIT (Austrian Institute of Technology), 17 partners from all over Europe are working on a multidisciplinary research agenda. Research institutes (AIT, Fraunhofer HHI, Interuniversity Microelectronics Center) with many years of experience in the transfer of academic basic research into industrial applications will work with quantum researchers with theoretical and experimental know how (University of Vienna, University of Paderborn, University of Innsbruck, Technical University of Denmark).
The project can also draw on photonics and electronics as well as integration and packaging expertise (Eindhoven University of Technology, Micro-Photon Devices, Politecnico Milano, Smart Photonics, Institute of Computer and Communication Systems of Athens, VPI Photonics, Cordon Electronics). The perspective of the industrial end users is being introduced by the system provider Mellanox and the operator Cosmote. Field evaluation will be conducted in a Smart City test environment operated by the University of Bristol.
"The Austrian Institute for Technology is a world leader in quantum communication. We are proud that we were selected by the consortium as a partner for integrated optics and that our technology platform PolyBoard contributed to the successful evaluation in the highly selective selection procedure of the EU," says Prof. Dr. Martin Schell, Executive Director of Fraunhofer HHI.

Abnormal scarring is a serious threat resulting in non-healing chronic wounds or fibrosis. Scars form when fibroblasts, a type of cell of connective tissue, reach wounded skin and deposit plugs of extracellular matrix. Until today, the question about the exact anatomical origin of these fibroblasts has not been answered. In order to find potential ways of influencing the scarring process, the team of Dr. Yuval Rinkevich, Group Leader for Regenerative Biology at the Institute of Lung Biology and Disease at Helmholtz Zentrum München, aimed to finally find an answer. As it was already known that all scars derive from a fibroblast lineage expressing the Engrailed-1 gene - a lineage not only present in skin, but also in fascia - the researchers intentionally tried to understand whether or not fascia might be the origin of fibroblasts.
