Introduction of QKD service in existing IT infrastructures

Quantum communication has reached a decisive technological milestone with the maturity of quantum key distribution (QKD). While the main focus has so far been on the physical-technological proof of feasibility, questions of practical implementation in existing IT infrastructures are now increasingly coming to the fore. What exactly should the use of QKD in operational IT environments look like? Which architecture models are suitable for smooth operation? And how can a QKD service be designed so that it is intuitive and scalable for the customer?

This presentation will provide an overview of how a QKD service can be provided in the context of existing networks and security architectures. Specific deployment scenarios will be presented - for example via trusted nodes, point-to-point routes or as part of an SDN-controlled network. Existing hurdles will also be addressed, such as the connection to applications, integration into VPN infrastructures or the challenges of key utilisation and management. The presentation shows that the transition from quantum physics to operational service provision requires above all interdisciplinary cooperation - between physics, network technology, IT security and the user side. The aim is to provide a practical understanding of the entry into an era of quantum-secured communication.
