Quantum computers will increasingly threaten the security of traditional encryption methods in the future. Quantum-secure options such as PQC (post-quantum cryptography) and QKD (quantum key distribution) offer ways to future-proof communication, especially in security-critical areas such as public administration, defense, and healthcare. A study coordinated by Fraunhofer ISI as part of the umbrella project Quantum Communication Germany (SQuaD) highlights the framework conditions, challenges, and promising application sectors for QKD – as well as potential that goes beyond QKD.
