INSIGHTS INTO QUANTUM COMPUTING FOR NEXT-GENERATION 6G WIRELESS NETWORKS

Abstract

Sixth-generation (6G) wireless networks must achieve unprecedented performance metrics, including terahertz (THz) frequency band communications, sub-millisecond latency, and hyper-dense device connectivity. The Quantum-Accelerated optimization and security framework (QAOSF) is introduced to address 6G network bottlenecks by integrating the Quantum approximate optimization algorithm (QAOA) for beamforming and a modified Harrow-Hassidim-Lloyd (HHL) algorithm for efficient multi-user detection. The framework enhances security by combining continuous-variable quantum key distribution (CV-QKD) with lattice-based cryptography while mitigating physical constraints through topological error correction and quantum repeaters.
