Array-Antenna Power-Pattern Analysis through Quantum Computing

A study on the analysis of the power-pattern of phased-array antennas (PAs) based on the quantum Fourier transform (QFT) is presented. The computation of the power pattern given the set of complex excitations of the PA elements is addressed within the quantum computing (QC) framework by means of a customized procedure that exploits the quantum mechanics principles and theory. A representative set of numerical results, yielded with a quantum computer emulator, is reported and discussed to validate the proposed method also pointing out its features in comparison with the classical approach based on the discrete Fourier transform (DFT).
