On February 03–06, 2022, the Workshop on Entanglement Assisted Communication Networks (EACN) took place at
Physikzentrum Bad Honnef. This event was a joint workshop of the Emmy Noether Group “Theoretical Quantum System
Design” supported by the Deutsche Forschungsgemeinschaft (DFG) and the Institute for Communications Engineering
supported by the German Federal Ministry of Education and Research (BMBF) with the project QR.X.
Topics: Will quantum communication reshape classical network design? What will be the next technological breakthrough in quantum communication? This interdisciplinary workshop focusses on entanglement as a resource assisting classical communication systems. We welcome participants from academic institutions, research labs and industry. Selected approaches to entanglement-assisted communication will be presented, along with established communication models in classical networking. To spark fruitful discussions, information regarding the progress in quantum hardware development will be provided.
