%D 2024 %X This study presents an analysis of the power pattern of phased-array antennas (PAs) using the quantum Fourier transform (QFT). Within the framework of quantum computing (QC), a tailored procedure is developed to compute the power pattern based on the complex excitations of the PA elements, leveraging the principles and theories of quantum mechanics. A representative set of numerical results, obtained using a quantum computer emulator, is reported and discussed to validate the proposed method, highlighting its features in comparison to the classical approach based on the discrete Fourier transform (DFT). %I ELEDIA Research Center - University of Trento %A Luca TOSI %A Paolo ROCCA %A Nicola ANSELMI %A Andrea MASSA %K Quantum Antennas, Array Synthesis %L elediasc12893 %T Quantum Computing for Analyzing Array Antenna Power Patterns
