Cortical Specification of a Fast Fourier Transform Supports a Convolution Model of Visual Perception [PDF]

open access: yes, 2012
Currently, the full extent of the role Fourier analysis plays in biological vision is unclear. Although we have examples of sensory organs that perform Fourier transforms, e.g.

Implementing Quantum Fourier Transform in a Digital Quantum Coprocessor [PDF]

open access: yesAdvances in Cyber-Physical Systems, 2019
In this paper, the digital quantum coprocessor has been checked for the possibility of quantum Fourier transform, which is the main quantum operation of the Shor's algorithm. To do this, the model of the 4-qubit coprocessor has been created, its work has been simulated and it has been implemented in FPGA.

Interpolating Binary and Multivalued Logical Quantum Gates

open access: yesProceedings, 2017
A method for synthesizing quantum gates is presented based on interpolation methods applied to operators in Hilbert space. Starting from the diagonal forms of specific generating seed operators with non-degenerate eigenvalue spectrum one obtains for ...

On Hausdorff-Young inequalities for quantum fourier transformations [PDF]

open access: yesUkrainian Mathematical Journal, 1997
Summary: The classical Hausdorff-Young inequality for the Fourier transformation is generalized to various quantum contexts involving noncommutative \(L^p\)-spaces based on translation-invariant traces.

A Step-by-Step Shor’s Algorithm Walkthrough: From Theory to Implementation

open access: yesIEEE Access
Quantum computing is inherently abstract and often counterintuitive from the perspective of classical physics. For learners to develop a deeper understanding, it is useful to study a practical example thoroughly, from its mathematical formalism to ...

Non-Uniform Quantum Fourier Transform

open access: yesCoRR
The Discrete Fourier Transform (DFT) is central to the analysis of uniformly sampled signals, yet many practical applications involve non-uniform sampling, requiring the Non-Uniform Discrete Fourier Transform (NUDFT). While quantum algorithms for the standard DFT are well established, a corresponding framework for the non-uniform case remains ...

Alcohol induced surface charging of colloidal quantum dots for controllable electrophoretic deposition processing

open access: yesNano Research
In this work, we report alcohol induced surface charging of colloidal quantum dots for controllable electrophoretic deposition processing. By adding a fixed amount of alcohol into a preformed quantum dots solution in non-polar solvents, quantum dots can ...

Double Quantum Image Encryption Based on Arnold Transform and Qubit Random Rotation

open access: yesEntropy, 2018
Quantum image encryption offers major advantages over its classical counterpart in terms of key space, computational complexity, and so on. A novel double quantum image encryption approach based on quantum Arnold transform (QAT) and qubit random rotation

Fourier-transforming with quantum annealers [PDF]

open access: yesFrontiers in Physics, 2014
We introduce a set of quantum adiabatic evolutions that we argue may be used as `building blocks', or subroutines, in the onstruction of an adiabatic algorithm that executes Quantum Fourier Transform (QFT) with the same complexity and resources as its gate-model counterpart.
