Abstract
The increasing need for IT security and potential threats posed by quantum computers for classical encryption have led to a growing interest in quantum-safe cryptography. When implemented correctly, quantum key distribution (QKD) promises a quantum-safe option for cryptography that can be used to communicate highly confidential information in a secure way. It therefore has great potential for sectors dealing with critical and secret information, such as the government, the military, and the medical sector. This report discusses application perspectives for QKD in various sectors, including network aspects, standardization and certification, which heavily influence QKD adoption. Further applications of quantum communication that go beyond QKD are also discussed.

Quantencomputer bedrohen in Zukunft zunehmend die Sicherheit klassischer Verschlüsselungsverfahren. Quantensichere Optionen wie PQC (Post-Quanten-Kryptographie) und QKD (Quantenschlüsselverteilung) bieten Möglichkeiten, die Kommunikation insbesondere in sicherheitskritischen Bereichen wie der öffentlichen Verwaltung, dem Verteidigungssektor oder dem Gesundheitswesen zukunftssicher zu machen. Eine vom Fraunhofer ISI im Rahmen des Schirmprojekts Quantenkommunikation Deutschland (SQuaD) koordinierte Studie beleuchtet Rahmenbedingungen, Herausforderungen und vielversprechende Anwendungssektoren von QKD – sowie Potenziale, die über QKD hinausgehen.
