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."

News at a Glance


Compact laser scanner with 90 percent less construction volume

Galvanometer scanners have been in use in laser material processing for decades. However, a team from the Fraunhofer Institute for Laser Technology ILT has now developed a new, particularly compact scanner module for applications in 3D printing, micromachining or medical technology. The researchers have already successfully tested it for various applications. The scanner will be on display at LASER World of Photonics 2023 in Munich.

Research Campus Digital Photonic Production celebrates Day of Light 2023

Humans have been using fire for two million years. Humans have lived in the glow of electric light for over 100 years. Light is energy, light is heat, light is the foundation of life in our world as we know it. Light has changed humankind in essential areas of life: for example, in medicine, in communication, in energy production.

Photonic Technologies for the Quantum Internet

Researchers at the Fraunhofer Institute for Laser Technology ILT are developing technology for quantum networks of the future. Funded by the state of North Rhine-Westphalia, the institute is installing hardware of a network node on location, as it is also used in the quantum internet demonstrator of QuTech in Delft in the Netherlands. The hardware will initially serve as a test and development platform, which the scientists want to use to develop new components for networking quantum computers with partners from industry and research on site in Aachen. In the future, the node is to be integrated into a European quantum network. Initial results will be presented at the "World of QUANTUM" trade fair in Munich at the end of June.

LASER World of PHOTONICS 2023: Premiere of the Arctic Kind

An electric snowmobile at LASER World of PHOTONICS 2023 in the summer! Why? Trade show visitors have the Finnish startup Aurora Powertrains Oy from Rovaniemi to thank for this premiere of the Arctic kind. Aurora has developed cold-resistant batteries with extremely high energy density for the Arctic temperatures of this region, and the customized joining technology required for this comes from the laser welding experts at the Fraunhofer Institute for Laser Technology ILT in Aachen.
