CESNET and Ribbon Achieve Successful Proof of Concept in Quantum-Secured Optical Networking

Demonstrates real-world viability of quantum encryption without performance tradeoffs

They demonstrated the practical feasibility of quantum encryption without compromising performance  

The CESNET consortium, in collaboration with Ribbon Communications Inc., has successfully tested the deployment of quantum key distribution (QKD) in a real-world optical network. The test confirmed that quantum encryption can be integrated into existing infrastructure without impacting its performance, paving the way for its practical use in both academic and commercial environments.

“Our mission is to ensure the highest possible level of security for academic and research communications,” said Václav Novák of CESNET. “This successful test builds on our long-term partnership with Ribbon and confirms that quantum encryption can be deployed in real-world optical networks without negatively impacting their performance.”

Ribbon’s Apollo optical network system delivers Layer 1 (L1) encryption with virtually zero latency and no additional overhead. It ensures the protection of both transmitted data and address information, which is unreadable to unauthorized parties. As a result, encrypted DWDM/OTN networks can transmit any client services without restrictions and without causing interoperability issues. Optical encryption thus represents an effective tool for protection against unauthorized access—the Apollo platform also allows it to be used internally or offered as a value-added service.

“QKD represents the future of secure networks,” said Christian Erbe, Ribbon’s Head of Sales for the EMEA region. “We are pleased to support CESNET and offer a security solution that is exceptionally resistant to breaches and ready to tackle next-generation threats.”
