Quantum Breakthrough: Secure Data Transmission Over 100km
Researchers have made a significant breakthrough in quantum encryption. A team from the Technical University of Denmark (DTU) has successfully transmitted information securely over a record 100 kilometers via fiber optic cable. This was achieved using a method called Continuous Variable Quantum Key Distribution (CV QKD).
The groundbreaking work was part of the QuNET initiative, a collaboration involving the German Aerospace Center (DLR) and multiple institutes in Jena, including the Fraunhofer Institute for Applied Optics and Precision Engineering (Fraunhofer IOF). The team used CV QKD to securely transmit data over the impressive distance.
This method offers a solution to the looming threat of quantum computers, which could potentially crack current encryption methods. By applying CV QKD to existing internet infrastructure, researchers aim to distribute quantum-encrypted information globally, enhancing data security on a vast scale.
The successful transmission of quantum-encrypted data over 100 kilometers marks a significant milestone. This achievement brings us closer to a future where secure communication is the norm, even in the face of advanced quantum threats. The team's work paves the way for integrating quantum encryption into global internet infrastructure.
