Madrid Quantum Communication Infrastructure: A testbed for assessing QKD technologies into real production networks

We report on the Madrid Quantum Communication Infrastructure, which demonstrates that a telecommunications network can also host quantum communications in a unified, logical and physical infrastructure. Using new Quantum Key Distribution systems paired with modern networking paradigms, we demonstrate a high technology readiness level of QKD installing the network in production facilities and running relevant use cases.

Increasing network reliability by securing SDN communication with QKD

Modern communication networks can be flexibly shaped and controlled using Software Defined Networking (SDN) paradigm. However, besides unprecedented functional benefits, this solution exploits an architectural single point of failure. Securing the communication among SDN functional element is therefore a critical requirement for improving the network reliability.

Demonstration of software defined network services utilizing quantum key distribution fully integrated with standard telecommunication network

We present a demonstration of software defined networking (SDN) services utilizing quantum key distribution (QKD) technology, fully integrated with standard telecommunication network connecting production facilities of Telefonica in Madrid. All communications “co-propagate” over the same fiber infrastructure. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.
