A Quantum Proxy Signature Scheme Without Restrictions on the Identity and Number of Verifiers
EntropyQuantum digital signatures (QDS) establish a framework for information-theoretically secure authentication in quantum networks. As a specialized extension of QDS, quantum proxy signatures facilitate secure delegation of signing privileges in distributed ...

Statistical Fourier Analysis: Clarifications and Interpretations [PDF]
This paper expounds some of the results of Fourier theory that are essential to the statistical analysis of time series. It employs the algebra of circulant matrices to expose the structure of the discrete Fourier transform and to elucidate the filtering

Advanced methods in fourier transform ion cyclotron resonance mass spectrometry [PDF]
Mass spectrometry (MS) is a powerful analytical technique used to characterize various compounds by measuring the mass-to-charge ratio (m/z). Among different types of mass analyzers, Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR ...

The multiresolution Fourier transform : a general purpose tool for image analysis [PDF]
The extraction of meaningful features from an image forms an important area of image analysis. It enables the task of understanding visual information to be implemented in a coherent and well defined manner.

Quantum arithmetic with the quantum Fourier transform [PDF]
Quantum Information Processing, 2017 The Quantum Fourier Transform offers an interesting way to perform arithmetic operations on a quantum computer. We review existing Quantum Fourier Transform adders and multipliers and propose some modifications that extend their capabilities. Among the new circuits, we propose a quantum method to compute the weighted average of a series of inputs in ...
