Danish Quantum Communication Infrastructure

ongoing

The Danish Quantum Communication Infrastructure (QCI.DK) is a concrete, detailed, and feasible yet highly ambitious proposal for realising a first deployment of advanced national quantum systems in a versatile network that supports real-life applications of Quantum Key Distribution (QKD). In QCI.DK we will establish a quantum secured metropolitan network between 5 Danish public authorities and 2 associated data centres in the Copenhagen area. In addition the infrastructure will encompass a 200 km long-distance link connecting three participating university partners via the metropolitan network. QCI.DK will combine three different QKD technologies in one network and thereby enable a broad range of tests and applications. To explore applications of QKD, the project devotes large attention to the development of use cases in the public authorities network and analysis of best implementations. This knowledge, together with essential practical experiences from the hardware implementation, will directly spill over into education, training, and outreach activities targeting the formation of a quantum aware workforce with proficiency in QKD and the creation of general quantum awareness in Denmark. Both future and existing workforce will be addressed through a combination of university teaching and up-skilling. The consortium behind QCI.DK spans a diverse group of stakeholders and unites public authorities, small and large private businesses, and academic institutions in a hitherto unprecedented strategic effort on deployment of quantum technology in Denmark. This makes QCI.DK an ideal technology demonstration project and an important spearhead for initiating large-scale deployment of quantum communication technologies with potentially far-reaching impact for the country.
