TNO delivers Germany’s first quantum internet node

Quantum technologies hold immense promise for the future. Quantum computing will solve classically intractable problems, and quantum sensing will enable unprecedented precision in measuring physical quantities. However, the quantum internet is the key to unlocking the full potential of these technologies. By connecting quantum devices, we can enhance their capabilities, enabling distributed quantum computing and quantum sensing networks.

Dutch-German Collaboration

Fraunhofer ILT and TNO have been working together on an ICON project to develop optical components for the quantum internet and quantum information. This fruitful collaboration has led to significant advancements, such as a quantum frequency converter (QFC) architecture with record performance in low noise and improved signal-to-noise ratio.

The collaboration has since expanded, incorporating the expertise of the entire Fraunhofer-Gesellschaft. Both parties plan to install the first German quantum node of a transnational quantum network at Fraunhofer ILT, serving as a testbed and stepping stone towards a European entanglement-based quantum internet. This quantum node was delivered to Fraunhofer on the 16th of January 2025.

Looking Ahead

This project represents a significant milestone towards a more secure and interconnected world. Future collaborations between Fraunhofer ILT and TNO are anticipated, as this is merely one of many foundational steps for the quantum Internet. The development of a second quantum node, quantum repeaters, and other essential components for a global quantum internet are on the horizon. The future looks promising for this collaboration.
