About the SnT...

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 towards quantum information systems.

Furthermore, our activities are experimentally driven and supported by the , the , the , our , and our OTA Facilities . For further information, you may refer to

The successful candidate will primarily contribute to the large EU research project Lux4QCI - Lux embourg Experimental Network for Q uantum C ommunication I nfrastructure).

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 fibres 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 looking for people driven by excellence, excited about innovation, and looking to make a difference. If this sounds like you, you have come to the right place!
