Integrating Quantum AI and Reconfigurable Intelligent Systems in 6G Networks

Objetivo

6G will transform wireless communications by delivering extreme data rates, ultra-low latency, and seamless connectivity, enabling applications such as XR, immersive communications, and massive IoT. Achieving these goals requires addressing major challenges in spectrum use, energy efficiency, coverage, and resilience. A key enabler for the multi-functional 6G networks (ISAC, wireless power transfer and physical layer security) will be the FR3 mid-band (7–24 GHz), which balances coverage and capacity better than FR1 or FR2. QUEST-6G introduces a framework combining reconfigurable intelligent systems, XL antenna arrays, new transmission modes, and quantum technologies to realize a multi-band, multi-functional 6G vision. XL arrays extend near-field regions, enabling beamfocusing with angular and range control for spatial multiplexing and interference management. Cell-free architectures with distributed RUs in WD-MIMO configurations, aligned with the ORAN paradigm, create hybrid near/far-field (NF/FF) conditions requiring new signal processing methods. The project designs reconfigurable, software-defined XL arrays as well as compact beam-steering frontends; develops hybrid NF/FF beamforming algorithms; and proposes adaptive waveforms, frame structures, and multiband coexistence schemes. It performs NF/FF FR3 channel sounding and modeling, implements an FR3 beamfocusing chip, and investigates accelerating “bending” beams. QUEST-6G proposes the integration of Quantum Technologies for accelerating the solution of optimization problems in the 6G environment. At system level, QUEST-6G applies quantum optimization and quantum ML for hybrid precoding, resource allocation, CSI prediction, and more, with deployment on both quantum platforms and edge devices. Finally, an AI-native intent-based RAN layer will translate high-level requirements into optimal configurations using semantic reasoning and explainable orchestration. Innovations will be validated via simulations, and PoCs.
