Quantum Communication

As digital communication moves toward a new, quantum-based era, quantum communication technologies are poised to redefine data security and information processing. By harnessing the principles of quantum mechanics, entirely new approaches are emerging to ensure integrity, confidentiality, and efficiency in communication systems.

The Fraunhofer IPMS conducts research on key building blocks of this technology – from Quantum Key Distribution (QKD) to Quantum Random Number Generation (QRNG) – developing industry-oriented solutions that are equally suited for scientific collaboration and technology transfer projects.

Quantum Key Distribution (QKD)

Quantum Key Distribution is one of the most promising technologies for next-generation cybersecurity architectures. It enables the absolutely secure exchange of encryption keys based on the laws of quantum physics – any attempt to intercept the communication can be detected immediately, as it alters the quantum system.

The Fraunhofer IPMS possesses extensive expertise in photonic integration, quantum optics, and secure communication systems. Building on this foundation, the institute develops scalable and practical QKD systems that can be integrated into industrial environments, critical infrastructures, and future quantum communication networks.

We offer:

• Development of QKD components and modules
• Integration of photonic systems into existing communication networks
• Joint research on standardization and interoperability
• Participation in national and European funding initiatives (e.g., Quantum Flagship, IPCEI, BMBF programs)

Quantum Random Number Generation (QRNG)

Quantum Random Number Generation exploits the inherent unpredictability of quantum mechanical processes to produce true randomness – a foundation for secure encryption, authentication, and simulations.

The Fraunhofer IPMS develops hardware-based QRNG solutions using integrated photonic technologies. These systems offer the highest level of trustworthiness and are optimized for use in security-critical applications ranging from cryptography and cloud infrastructures to quantum metrology.

We offer:

• Development and validation of QRNG hardware
• Integration into communication and sensor systems
• Joint research on quantum randomness and signal processing
• Test environments for industrial partners and research institutions

Collaboration 

Fraunhofer IPMS acts as a bridge between fundamental research, applied development, and industrial implementation. For funding agencies, research institutions, and industry partners, the institute offers:

• state-of-the-art infrastructure for photonic and quantum-optical systems, 
• extensive experience in the management of publicly funded research projects, and
• active participation in national and European quantum initiatives.

Together, we shape the future of secure communication – from quantum photons to industrial networks.
