On September 10-12, 2025, the Workshop on Entanglement Assisted Communication Networks (EACN) took place at EURECOM, Sophia Antipolis near NICE, France in the French Riviera.
Topics: Shared entanglement is widely acknowledged as the key enabler to future quantum information processing tasks. Yet, from a technological perspective, it has remained largely unclear how exactly one should approach the transfer from ideas and laboratory experiments to actual technology. In particular this is true for the domain of quantum communication. To find answers to multidisciplinary questions connecting theory, experiment and network design, this interdisciplinary workshop focuses on entanglement as a resource assisting classical communication systems, covering topics such as Quantum Memories, Quantum Simulators, Entanglement Generation and Quantum Security. We welcome participants from academic institutions, research labs and industry.
