Research Associate (Postdoc) in SDN/NFV

The SIGCOM research group is headed by Prof. Symeon Chatzinotas, and mainly carries out research activities in the areas of signal processing for wireless communication systems, including satellite communications, and is currently expanding its research activities toward quantum information systems. Furthermore, our activities are experimentally driven and supported by the SDR CommLab, the SDN Lab, the 5G-Space Lab, our SW Simulators, and our OTA Facilities.

The successful candidate will primarily contribute to the large EU research project Lux4QCI Luxembourg Experimental Network for Quantum Communication Infrastructure). The project is part of the Digital Europe Program (DIGITAL) and aims to deliver the first experimental quantum communication infrastructure (QCI) network in Luxembourg. A distinctive feature is the by-design integration between the terrestrial and the satellite segment. Lux4QCI envisions making Luxembourg a QCI front-runner and a hub for secure key distribution across the EU. To achieve those goals, Lux4QCI will identify use cases of interest for application scenarios of quantum key-distribution (QKD)-enhanced secure communications. The intended QCI will be nationally deployed through multiple terrestrial optical fibers running hundreds of kilometers and interconnecting at least 5 points of presence. The network will rely on a hybrid configuration combining multiple QKD technologies over a range of multihop topologies (e.g., star, serial, and tree). The intended architecture contains an orchestrator collocated with a node. The orchestrator consists of a network manager with SDN/network-function virtualisation (NFV) algorithms for flow management/routing, a quantum key-distribution network (QKDN) controller, which performs routing control of key relay, and a QKDN manager, which monitors the status of the QKDN and assists the key management system (KMS) for key-management operations.

We are seeking a highly qualified Research Associate candidate with expertise in software-defined networking (SDN) and network function virtualization (NFV) to join our Quantum Key Distribution project. The ideal candidate will possess not only a solid theoretical understanding of these technologies, but also a demonstrated ability to apply their knowledge through hands-on experience. We are looking for an individual who is able to thrive in a dynamic and fast-paced environment, and who is committed to driving innovation and advancement in the field of SDN, NFV, and Quantum Key Distribution.
