Abstract:
Our work explores the integration of quantum technologies with semantic communications to address the challenges related to transmitting semantic systems over traditional communication channels. As communication systems evolve to support knowledge exchange and reasoning among natural and artificial intelligent agents, they face critical inefficiency, inaccuracy, and high system complexity, particularly when conveying structured, contextual data representation. To overcome these limitations, we propose a novel paradigm called quantum semantic communications (QSC), which merges quantum information science with semantic communication principles to enable efficient, robust, and goal-driven information exchange.
At the core of QSC is the transmission of semantic representations rather than raw data using quantum-enhanced encoding, transmission, and decoding mechanisms. Semantic features are extracted from knowledge graphs using pre-trained language models and graph neural networks and then encoded into quantum states for efficient and resilient transmission across noisy channels. We further extend this paradigm with quantum semantic sensing (QSS), a complementary architecture that enables multi-sensor semantic fusion and transmits only task-relevant, compressed semantic content aligned with specific inference goals. Semantic validation at the receiver is performed using quantum interference, ensuring both accuracy and relevance. This work offers a framework for efficient, resilient, and context-aware communication, laying a foundation for quantum-semantic integration in next-generation intelligent networks.
