Between February 24–28, as part of the EU flagship initiative SEQRET – Secure and Industrialized Quantum Key Distribution for European Telecom Networks, EXATEL and KEEQuant conducted a series of tests on Quantum Key Distribution (QKD) technology using the live infrastructure of #EXATEL.
During the test phase, the partners successfully established quantum communication in the presence of classical signals, marking a key step forward in the real-world deployment of quantum-secure technology. A particular highlight was the test of KEEQuant’s CV-QKD solutions with DWDM systems. The results showed the high potential for compatibility with lit fiber environments, indicating a viable path towards seamless coexistence with existing telecom infrastructure.
This is part of a broader effort led by KEEQuant within the SEQRET project, funded by the Digital Europe Programme, to develop scalable, certifiable, and user-oriented QKD technologies. Our CV-QKD approach – featured in the Andariel Testbed Series – is currently the only QKD solution capable of full chip-level integration.
What does this mean for the future? Thanks to its compact form factor, low power usage, and manufacturing potential, CV-QKD stands as a strong candidate for wide-scale commercial deployment. By aligning closely with the operational needs of telecom providers like EXATEL, we’re laying the groundwork for secure, next-generation communication networks.
