Secure data transfers are necessary in the fight against cybercrime and now researchers at the Danish Technical University (DTU) have accomplished secure transfer of data using quantum technology.
The success emphasises the world-class Danish quantum ecosystem, where universities and actors from the private sector collaborate to bring quantum technology out of the labs and implementing it.
In collaboration with the consultancy company KPMG, DTU has succeeded in encrypting a data transfer between two of Danske Bank's computers, simulating communication between the bank’s data centers.
The event marks the first successful encryption of a data transfer using quantum technology outside laboratories in the Nordic region.
We are very proud to help the researchers reach this milestone and at the same time gain first-hand experience of quantum-safe data transfer, which potentially has great significance for the future security of digital communicationLance McGrath

Quantum safe data transfer is based on ‘continuous variable quantum key distribution’ (CV-QKD)-technology. Quantum key encryption uses quantum physics to secure the distribution of symmetric encryption keys. The technology enables the creation and sharing of secure encryption keys with the help of standard telecom fibre optics.
Our approach uses the fundamental unpredictability and randomness of quantum mechanics as the source of security. This way we create the foundation for data transfers that are impossible to hack unless you break the laws of physicsTobias Gehring
Associate professor at DTU
The project which resulted in the
successfully quantum encryption, CryptoQ, is funded by Innovation Fund Denmark and aims to ensure a position for Denmark on the global market for secure and
cost-efficient quantum communication technology.
