Antenna Array Thinning Through Quantum Fourier Transform

open access: yesIEEE Access, 2021
Thinning antenna arrays through quantum Fourier transform (QFT) is proposed. Given the lattice of the candidate locations for the array elements, the problem of selecting which antenna location has to be either occupied or not by an array element is ...

Quantum states of a particle in a box via unilateral Fourier transform [PDF]

open access: yesRevista Brasileira de Ensino de Física, 2020
The quantum problem of stationary states of a particle in a box is revisited by means of the unilateral Fourier transform. Homogeneous Dirichlet boundary conditions demand a finite Fourier sine transform which is actually the Fourier sine series.

A quantum multiplier based on the quantum Fourier transform algorithm

open access: yesDianzi Jishu Yingyong, 2022
Multiplier is one of the basic units in many quantum algorithms. In order to implement the multiplying operations and use as few auxiliary qubits in the quantum circuit as possible, a quantum multiplier based on the quantum Fourier transform is proposed.

Digital-analog quantum algorithm for the quantum Fourier transform

open access: yesPhysical Review Research, 2020
Quantum computers will allow calculations beyond existing classical computers. However, current technology is still too noisy and imperfect to construct a universal digital quantum computer with quantum error correction.

Random fractional Fourier transform : stochastic perturbations along the axis of propagation [PDF]

open access: yes, 1999
The fractional Fourier transform (FRT) is known to be optically implementable with use of a medium with a perfect radial quadratic-index profile. Using the quantum-mechanical operator formalism, we examine the effects on the FRT action of such a medium
