We are excited to announce a major technology milestone: KEEQuant’s Andariel Testbed Series CV-QKD systems now support 16 dB channel loss!

Why is this big news? Because 16 dB reach (80 km in standard telecom fiber) means that continuous-variable QKD is no longer limited to short links—it’s now viable not just for metro and regional, but also for long-haul, core, and data center interconnect networks, broadening its real-world application space. 🚀 This breakthrough brings us a step closer to real-world deployment at scale, making CV-QKD the scalable option for securing critical infrastructure.

✅ Security matters: Our security proofs are well-founded and sound.
➡️ What’s next? Even more reach, full certification, and further miniaturization using photonic integrated circuits (PICs).

The future of quantum-secure communication is here—and we are just getting started. 💡

We’re thrilled to share that the Karlsruhe Institute of Technology (KIT) has officially launched a groundbreaking test of quantum key distribution (QKD) for secure communication networks, as highlighted here

At KEEQuant, we’re proud to have provided our Andariel Testbed Series QKD system for the link. A huge thank you to all our partners and supporters who made this possible, including but not limited to Sebastian Randel , David Hunger and Patrick Matalla who made this impressive presentation possible. Your expertise and dedication are key to driving innovation forward!

Together with our partner CESNET, a provider of IT services for academia and science in the Czech Republic, we are performing integration tests of Quantum Key Distribution (QKD) into the CESNET campus network to prepare solutions for a quantum-safe future. This is part of the EU flagship project SEQRET, led by KEEQuant and funded by the Digital Europe Programme. The project’s goals are to provide customer-centric, certifiable and scalable QKD solutions.

The KEEQuant “Andariel Testbed Series” product relies on Continuous-Variable QKD (CV-QKD). It is currently the only QKD technology that can be fully chip-integrated. Consequently, in the future, high-volume manufacturing and lower manufacturing costs will become tangible for CV-QKD, which is going to lead to a more widespread adoption of the technology. Further advantages of an integrated solution are significant reductions in size, weight, and power consumption, along with improved ruggedness of QKD.

With the collaboration between CESNET and KEEQuant, both parties ensure that the engineering of the CV-QKD device is aligned with real-world network requirements. This will be further explored in the collaboration within the SEQRET project.

Stay tuned for more updates on how we are securing the future of communication!

We are excited to announce that the DemoQuanDT project has successfully entered live operation! 🎉 Over a 900+ km quantum-secured network across Germany, between Berlin and Bonn, we demonstrated real-time Quantum Key Distribution (QKD), including dynamic routing of quantum-secured connections.

📍 Live Demo in Berlin
At the official demonstration in Berlin, representatives from the German Federal Ministry of Education and Research (BMBF) witnessed the system in action, showcasing how QKD can be integrated into modern communication networks using additional components like KEEQuant’s key management system KMS1 Evaluation Series. This marks a major step toward a scalable and interoperable quantum-secured infrastructure.

🔑 Why is this important?
The project’s focus on carrier network integration and the underlying architecture aspects provide a blueprint for similar and future quantum networks. A prominent example is the EuroQCI infrastructure spanning across the European Union. Additional features like cross-border networks and inter-carrier-network links are supported .

👏 A huge thank you to all project partners:

Speaking with the words of our host, we definitely enjoyed the liveliness of the QKD ecosystem at the SQuaD-Workshop@MuQuaNet. We contributed with talks and panel discussions and enjoyed the personal meetings all along the three days in Neubiberg. Looking forward to the next meeting at PTB!

Was braucht es noch um Quantenkryptographie zur breiten Anwendung zu bringen und unsere kritischen Infrastrukturen abzusichern? Frank Grotelüschen vom Deutschlandfunk hat dazu Ulrich Eismann im Rahmen der sehr hörenswerten Podcastreihe “Quantentechnologie im Realitätscheck” interviewt. Die kurzweiligen sechs Minuten werden heute Nachmittag 16:35 ausgestrahlt und sind jederzeit als Podcast verfügbar.

Two days of lively discussions about creating a QKD Post-Processing stack for the well-known protocol families of CV-QKD, DV-QKD, and EB-QKD. We are very happy to get into the details of the project with our partners: FAU Erlangen-Nürnberg , Ludwig-Maximilians-Universität München , Fraunhofer Heinrich Hertz Institute HHI , Fraunhofer IOF , Technische Universität Darmstadt, and VPI Photonics. We will keep you posted on our results in the next 3 years, so stay tuned!

We spent a great day at the European Commission‘s offices attending the EuroQCI (European Quantum Communication Infrastructure) project’s kickoff. All 26 national testbed projects were showcasing their plans for the first round of testbeds. The 5 industrial projects’ representatives presented their ways of improving QKD technology from EU-27. In this group, KEEQuant is coordinating the SEQRET project (stay tuned for more details) and its main goals

• CV-QKD from EU-27
• certifiability of CV-QKD
• scaling CV-QKD through photonic integration

Finally, the overarching PETRUS project showed its scope. Exciting times ahead for quantum cryptography in Europe!

Two days of OPENQKD’s Madrid event are over, what a ride! The European and international QKD elite was united with a very nice representation of the entire value chain. We had numerous chats about KEEQuant’s plans and capabilities, and we are looking forward to the EuroQCI kickoff early next year.
