Conventional encryption methods could be compromised by quantum computers in the next 5 to 10 years. Quantum secure communication is being developed to counter these future threats with new, robust encryption methods.
Quantum Communication Infrastructure
Quantum-safe communication uses the principles of quantum mechanics to ensure the long-term security of modern communication systems.
Are you still encrypting or are you already beaming? CANCOM offers solutions for quantum-safe data transmission.
Quantum-safe communication - how does it work?
A central element of the European Quantum Communication Infrastructure (EuroQCI) is Quantum Key Distribution (QKD), a core component of modern quantum-based systems. This technology utilises the laws of quantum physics to generate cryptographic keys in a physically secure manner. It uses individual light particles (photons) that can fend off attacks from quantum computers and maximise security, reliability and cyber security.
The QKD thus forms a foundation for secure digital communication and plays a key role in establishing a tap-proof, European quantum communication infrastructure that covers both the terrestrial segment and, in the long term, the space segment. As part of the EU initiative for secure quantum communication, it is to be established nationally and at strategic locations at national and cross-border level by 2025. It supports the EU member states in establishing powerful, robust communication infrastructures that can also withstand future threat scenarios.
Another central concept within the EuroQCI is post-quantum cryptography (PQC). These cryptographic methods are based on novel mathematical principles and were developed with quantum computer attacks in mind. PQC is purely software-based, can be easily integrated into existing systems, networks and data centres and ideally complements QKD - both nationally and in Europe. The European Commission, the FFG (Austrian Research Promotion Agency) and programmes such as CEF or ESA initiatives are strengthening current research, tenders and projects in the field of secure quantum-based communication infrastructure (2024-2025).
PQC and QKD can be combined to create hybrid encryption. In very simplified terms, a QKD system "beams" quantum-secure encryption keys for symmetric procedures, which can then be used in various applications (e.g. VPN services or critical infrastructures). PQC increases flexibility and supplements quantum physical security with additional software-based protection mechanisms. Together, the two technologies contribute to building a robust European ecosystem for secure quantum communication and future national quantum communication networks.

FAQs
The most frequently asked questions about Quantum Communication Infrastructure
- Why is quantum-safe communication becoming increasingly important for companies?
With advances in quantum computing, conventional encryption could soon become vulnerable. Quantum-safe solutions offer long-term protection by being based on physically and mathematically new principles that can withstand even quantum attacks.
- How does Quantum Key Distribution (QKD) differ from traditional encryption methods?
QKD uses individual photons for key distribution and makes use of a physical law that makes undetected eavesdropping impossible. This achieves a completely new level of security that goes beyond conventional methods.
- Which industries benefit most from quantum-safe technology?
Sectors with high security requirements - such as energy, healthcare, finance, aviation and public authorities - can make their communication infrastructure fit for the future and tap-proof by using quantum-safe connections.
- What role does Post-Quantum Cryptography (PQC) play in CANCOM's solution?
PQC is based on new mathematical methods that cannot be cracked by quantum computers. In combination with QKD, this results in a hybrid security concept that can be integrated into a wide range of applications such as VPNs.
- What exactly does CANCOM offer in the field of quantum-safe communication?
