Characterizing an Uncertainty Diagram and Kirkwood–Dirac Nonclassicality Based on Discrete Fourier Transform
In this paper, we investigate an uncertainty diagram and Kirkwood–Dirac (KD) nonclassicality based on discrete Fourier transform (DFT) in a <i>d</i>-dimensional system. We first consider the uncertainty diagram of the DFT matrix, which is a transition matrix from basis <inline-formula...
