  A method for the analysis of the power pattern of phased array antennas (PAs)
based on the quantum Fourier transform (QFT) is proposed. 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 assess the reliability of the proposed
method by pointing out its features in comparison with the classical approach
based on the discrete Fourier transform (DFT), as well.
