Celare Quantum Communications installs QKD systems in the Danish Ministry of Defence
Earlier this week, the Forsvarsministeriet installed Quantum Key Distribution (QKD) systems from Celare Quantum Communications.
The QKD solution provides future-proof quantum encryption, helping to secure communications for private companies, defence ministries, and other government institutions.
As part of NATO DIANA’s 2026 cohort, Celare has recently benefited from DIANA’s network and support. According to Celare’s CSO, Tobias Gehring, that experience has played a defining role in the company’s growth and recent successes:
“Our collaboration with partners and participation in the NATO DIANA accelerator has provided us with insights and a network that allows us to transform research into real quantum products at a much faster pace. This has led us to a new stage where we can truly make a difference for secure communications and thereby for the national security of NATO Allies,” he said.
Quantum Key Distribution (QKD) Systems from Celare Quantum Communications installed in the Danish Ministry of Defence
Last week the Danish Ministry of Defence (Forsvarsministeriet), installed Quantum Key Distribution (QKD) systems from Celare Quantum Communications.
The Ministry of Defence is one of four Danish ministries integrating the new technology into their IT-systems. The integrations are part of the QCI (Danish Quantum Communication Infrastructure) project funded by the European Commission, a collaboration of government institutions, universities, and private sector companies to implement and test quantum-secure infrastructure.
This is a big step towards our ambition to provide future-proof protection for data networks and critical infrastructure. The ability to transfer data securely is an important part of national security. As providers of a dual-use technology, Celare is also part of the NATO DIANA defence accelerator through our collaboration with BioInnovation Institute (BII).
The QKD System from Celare offers the exchange of secret keys for data encryption, using randomness based on the quantum states of light. This is a new form of symmetric key distribution based on the laws of quantum physics that offers future-proof protection against attacks from quantum computers. The Continuous Variable (CV) quantum approach allows the QKD technology to work within existing fibre telecom networks without modifications.

GlobalConnect and Celare Quantum Communications join forces to show the practical implementation of quantum encryption to secure fiber networks
At the V2 Security conference in Copenhagen Thursday, GlobalConnect CEO Martin Lippert presented how cyberattacks on our encrypted data networks are a real and growing threat, not only to our privacy, but also to critical infrastructure and the foundation of a stable and safe society.
QKD (Quantum Key Distribution) systems offer a solution to this problem.
At Celare, we supply the CV-QKD systems that allow network owners to transition to a quantum-resilient model without changing or disrupting their operations and infrastructure. The partnership with GlobalConnect shows how this transition is already happening.
This was the subject of another presentation at V2, where our CSO Tobias Gehring and Ekin Önder, PhD from GlobalConnect presented a practical example of how a commercial fiber line is quantum-secured. By combining GlobalConnect’s network and Celare’s QKD equipment, quantum-generated keys can be integrated into existing network architectures while maintaining operational scalability.
We look forward to continuing the collaboration with GlobalConnect to provide future-proof security for fiber networks using our QKD technology!
Celare Quantum Communications to contribute as a partner in the QGRID project
With the support of Innovationsfonden, we are proud to assist in protecting critical infrastructure with quantum-secure communications and intelligent fiber cables as partner in the QGRID project.
CEO Asger Trier Bing underlines the importance of participating in the project:
“Working with key partners to assist in securing data networks with quantum encryption in the QGRID project is exactly the right way forward, as this technology is already critical for securing our communication networks now and in the post-quantum future”, he says.
With a combination of quantum technology and intelligent fiber sensors, the new research and innovation project QGRID will make it possible to both protect data and detect physical intrusion in real time.
Celare Quantum Communications develops the quantum technology solutions for the project together with DTU Physics. Fluves and DFM – Danmarks Nationale Metrologiinstitut contribute with fiber sensors and data analysis, Terma Group with security and threat understanding, while Energinet and GlobalConnect make it possible to test the solution on existing networks in real operating environments.
Innovationsfonden is investing 13.8 million kroner in the project which will have a duration of three years.
€2.5M grant from the European Innovation Council (EIC) awarded to Celare Quantum Communications
We’re thrilled to announce that Celare Quantum Communications has been awarded a €2.5M grant from the European Innovation Council (EIC). This funding will support the continued development and scaling of our Quantum Key Distribution (QKD) technology, which already delivers quantum-secure encryption solutions to several clients. CEO Asger Trier Bing comments: “We look forward to putting this grant to good use by enabling even more companies and organisations to benefit from the safety and security of high-speed quantum-encrypted communications. This marks another important step toward making our technology a foundation for the secure communication networks of the future.” Celare’s proposal is one of just 40 projects selected from 611 submissions in the 2025 EIC Transition call. As part of the programme, Celare will also gain access to EIC Business Acceleration Services, including coaching, mentoring, and partnering opportunities.
