zerothird GmbH Deploys QKD in Live Finance System

zerothird GmbH reports demonstrating a functional entanglement-based quantum key distribution (QKD) system integrated directly into a live financial network, sustaining secure key generation over a 22 kilometer fiber link despite 8 decibels of signal loss. The fully automated setup maintained an average secure key generation rate of 63.8 kilobits per second for four continuous months, feeding directly into a VPN tunnel and establishing a new benchmark for practical quantum cryptography beyond laboratory settings. Achieving 93.7% total uptime, with no failures originating from the quantum optical components, addresses a critical concern regarding the reliability of these technologies in real-world applications. This deployment establishes a reference for the maturity of eQKD in operational environments and provides a foundation for the development of scalable eQKD networks. A secure key generation rate averaging 63.8 kb/s…
