Quantum‐Inspired Fourier Transforms Based on Circuits [PDF]

open access: yesAdvanced Science
Fourier transform (FT) is ubiquitous in modern society due to their broad applications in many branches of science and engineering. Improving the speed of FT is a common interest in the fields of signal processing. The quantum FT is generally believed to

Building a symbolic computer algebra toolbox to compute 2D Fourier transforms in polar coordinates [PDF]

open access: yesMethodsX, 2015
The development of a symbolic computer algebra toolbox for the computation of two dimensional (2D) Fourier transforms in polar coordinates is presented. Multidimensional Fourier transforms are widely used in image processing, tomographic reconstructions ...

Generalized Fourier-Mukai Transforms [PDF]

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 1996
The paper sets out a generalized framework for Fourier-Mukai transforms and illustrates their use via vector bundle transforms. A Fourier-Mukai transform is, roughly, an isomorphism of derived categories of (sheaves) on smooth varieties X and Y.

New many-parameter Fourier–Clifford transforms

open access: yesЦифровые модели и решения, 2023
The article shows how ordinary complex-valued Fourier transforms are extended to Cliffordean-valued many-parameter Fourier transforms (MPFCTs). Each MPFCT depends on finite set of independent parameters (angles), which could be changed independently one ...

Fractional Fourier transforms of vortex Hermite-cosh-Gaussian beams

open access: yesResults in Optics, 2021
In this paper, we investigate the propagation properties of a vortex Hermite-cosh-Gaussian beam (vHChGB) passing through a fractional Fourier transform (FRFT) optical system.

Different computational approach for Fourier transforms by using variational iteration method

open access: yesJournal of New Results in Science, 2022
In this paper, we present another method for computing Fourier transforms of functions considering the Variational Iteration Method (VIM). Through our procedure, the Fourier transforms of functions can be calculated precisely and without reference to ...
