1240 kilometres of fiber. Equivalent to the distance between Paris and Copenhagen.

- This is the length of the new quantum safe infrastructure to be deployed across the Nordics and Europe.

Within the coming three years quantum proof communication becomes reality across the Nordic region. Sensitive data will be safeguarded by integrating quantum safe systems into existing communication infrastructures. Confidential information, including ministerial and diplomatic correspondence, may now be securely transferred avoiding hacking or intrusive attempts.

The QCI.dk-Cross Border project extends the EuroQCI initiative by connecting existing ‘islands’ of national quantum communications infrastructures (QCIs) already deployed between 2023-2026. By creating a bridge between these infrastructures in Sweden and Poland, linking Denmark, Sweden (and potentially Finland) to the broader European quantum network, including all the 27 EU member states at the final stage.

The objective is to create an infrastructure for the secure exchange of encryption keys, based on Quantum Key Distribution (QKD) technologies, enhancing communication security and identity confirmation. The project is developing cross-border quantum networks, ensuring interoperability with the EuroQCI’s space segment, and managing encryption keys securely.

Harvest now, decrypt later: How is classified and confidential information kept safely in the Era of Quantum?

Health data, financial information, critical infrastructure, and public communication need to be protected from cybercriminals who can already now intercept encrypted data and decrypt it later by using quantum computing.
Quantum technology is threatening both personal and sensitive governmental data making safeguarding an urgent societal challenge rather than a distant tech problem.

QCI.dk-Cross Border Project Launch: Pan-European Quantum Communication is coming closer!

April 20, 2026 - Anne Mette Persdotter

Sweden, Denmark, and Poland have recently launched the EU Funded QCI.dk Cross Border Project with a duration of 42 months. During the coming years, the project partners will be deploying a secure, interoperable quantum communication infrastructure based on Quantum Key Distribution (QKD) technologies across the EU Member States. Thereby they will be contributing to the wider interoperable European Quantum Communication Infrastructure (EuroQCI) initiative.
