Fast Quantum-Inspired Algorithm for Beamforming

This paper presents a fast quantum-inspired algorithm to tackle the NP-hard beamforming problem in MIMO arrays. The proposed method achieves high-bit phase optimization with over a 1000-fold speedup compared to genetic algorithms while maintaining near-ground-state solutions. Tests on various array sizes demonstrate the algorithm's scalability, stability, and near real-time performance for small-size arrays, confirming its potential for large-scale electromagnetic optimization.
