As one of the key technologies of the 21st century, quantum technology (QT) offers enormous potential for the fields of health, mobility, energy and security, among other areas.

The "N-Quik" project, funded by the Ministry of Economic Affairs, Industry, Climate Protection and Energy of the State of North Rhine-Westphalia (MWIKE), is a new milestone in quantum technology research. Together with the Dutch QuTech - a collaboration of the TU Delft and the Netherlands Organization for Applied Scientific Research TNO - the Fraunhofer ILT will establish cross-border QT networks in the future. On February 13, 2023, NRW Minister of Economic Affairs Mona Neubaur handed over the funding notification for "N-QUIK" worth 3.5 million euros to Prof. Constantin Häfner, Director of the Fraunhofer ILT in Aachen.

The international project partners aim to have the quantum Internet node up and running by 2024. Prof. Constantin Häfner, Director of the Fraunhofer Institute for Laser Technology ILT: "This development and test platform for network components in NRW lays the foundation for taking a leading position in the development, implementation and exploitation of quantum technology. The forward-looking project "N-Quik" forms the starting signal for a quantum network in Europe."

5th Laser Symposium Electromobility LSE'23:
The perfect symbiosis of science and business

After three long years of meeting online, the industry finally convened live at the 5th Laser Symposium Electromobility LSE at the Fraunhofer Institute for Laser Technology ILT in Aachen. Around 50 interested parties accepted the invitation to hear speakers from research and industry report on progress, trends and ideas to further advance electromobilization. Highlights included a presentation by a Finnish snowmobile manufacturer, a 32-beam 100 kilowatt laser from Israel and insight from an Austrian AI expert.

New lasers for climate research

Weather reports, climate models or rocket launches – they all need precise data from the atmosphere. To acquire such data, scientists can use LIDAR (LIght Detection And Ranging) systems to shoot laser beams into the sky. The backscattered light can be used to calculate wind and temperature data at altitudes of up to 100 km. A team from the Fraunhofer Institute for Laser Technology ILT and the Leibniz Institute for Atmospheric Physics IAP has developed a portable LIDAR system that works autonomously. In the future, such systems could be mass-produced and combined into networks to provide high quality climate data.

IDEEL Project: Manufacture of laser-dried anodes and LFP cathodes achieved first time in a roll-to-roll process

The IDEEL research project aims to introduce a laser drying process as a more climate-friendly and economical method for the volume production of lithium-ion batteries. Within this context, it has now been possible to produce laser-dried anodes and LFP cathodes in a roll-to-roll process for the first time. The innovative manufacturing process significantly reduces energy consumption in electrode production and at the same time enables the drying speed to be doubled.
