Application Perspectives in Quantum Communication

This report discusses the application perspectives in quantum communication, focusing on Quantum Key Distribution (QKD) and its relevance in various sectors. It outlines the increasing need for IT security and the potential threats posed by quantum computers to classical encryption methods. The report highlights that QKD can provide a quantum-secure option for cryptography, particularly in sectors dealing with sensitive information, such as public administration, military, and healthcare. It details the current state of secure communication and the regulatory frameworks that influence the adoption of QKD, including EU directives aimed at enhancing cybersecurity. The report also addresses the challenges facing QKD technology, such as distance limitations and the need for trusted nodes or quantum repeaters for long-distance communication. Furthermore, it discusses the broader applications of quantum communication beyond QKD, emphasizing the importance of understanding sector-specific regulatory conditions for effective implementation.
