Overview

• The Karlsruhe Institute for Technology (KIT) has established a 20-kilometer glass fiber test network to explore quantum communication technologies.
• This testbed supports the transmission of quantum keys, which are critical for secure, eavesdropping-resistant communication in a highly connected world.
• Quantum communication is seen as a key technology to safeguard data against threats posed by both modern and future quantum computers.
• The initiative is part of broader efforts to develop a quantum internet, including research on quantum repeaters for secure long-distance data transmission.
• The German Federal Ministry of Education and Research is funding related projects, emphasizing the need for national independence in quantum technology development.
