Advancing Semantic Representation, Alignment, and Reasoning in Multi-Agent 6G Communication Systems
Semantic communications is an emerging and transformative research area, where the focus shifts from transmitting raw data to conveying meaningful information. While initial models and design solutions have laid foundational principles, they often rest on strong assumptions regarding the extraction, representation, and interpretation of semantic content. The advent of 6G networks introduces new challenges, particularly...

Enhanced Quantum-Radiofrequency Sensor
In the last decade, sensor systems using Rydberg atoms have been seen as a breakthrough solution to the problems of receiving radio frequency (RF) electromagnetic waves. The characteristics of this type of receiver are promising: extreme sensitivity, very wide bandwidth, miniature size independent of wavelength and no coupling to the immediate environment. All these advantages...
