Wigner distribution of twisted photons [PDF]
Physical Review Letters, 2015 We present the first experimental characterization of the azimuthal Wigner distribution of a photon. Our protocol fully characterizes the transverse structure of a photon in conjugate bases of orbital angular momentum (OAM) and azimuthal angle (ANG).

Wigner distributions for gluons [PDF]
European Physical Journal C: Particles and Fields, 2018 We investigate the gluon Wigner distributions for unpolarized, longitudinally polarized and transversely polarized target state. Instead of a nucleon, we take the target state to be a quark dressed with a gluon at one loop and investigate the gluon ...

A Wigner Quasiprobability Distribution of Work
Entropy, 2023 In this article, we introduce a quasiprobability distribution of work that is based on the Wigner function. This proposal rests on the idea that the work conducted on an isolated system can be coherently measured by coupling the system to a quantum ...

Wigner function and the probability representation of quantum states
EPJ Web of Conferences, 2014 The relation of theWigner function with the fair probability distribution called tomographic distribution or quantum tomogram associated with the quantum state is reviewed.

Fractal and FractionalIn order to achieve time–frequency superresolution in comparison to the conventional Wigner distribution (WD), this study generalizes the well-known τ-Wigner distribution (τ-WD) with only one parameter τ to the multiple-parameter matrix-Wigner ...

Wigner Distribution Sets Universal Lower Bound for Quantum Advantage in Gaussian Boson Sampling [PDF]
EntropyThe computational complexity, or quantum advantage, of Gaussian boson sampling is ascribed to squeezing of the Wigner quasiprobability distribution. This approach reveals the physical origin of the quantum complexity resource.

Six-dimensional light-front Wigner distribution of hadrons
Physics Letters B, 2022 We propose a six-dimensional light-front Wigner distribution for the complete description of partonic structures of a hadron such as pion and proton, taking advantage of the recently proposed light-front variable z˜ by Miller and Brodsky.

The affine Wigner distribution
Applied and Computational Harmonic Analysis, 2022 We examine the affine Wigner distribution from a quantization perspective with an emphasis on the underlying group structure. One of our main results expresses the scalogram as (affine) convolution of affine Wigner distributions. We strive to unite the literature on affine Wigner distributions and we provide the connection to the Mellin transform in a ...

A Novel GNSS Interference Detection Method Based on Smoothed Pseudo-Wigner–Hough Transform
Sensors, 2021 This paper develops novel Global Navigation Satellite System (GNSS) interference detection methods based on the Hough transform. These methods are realized by incorporating the Hough transform into three Time-Frequency distributions: Wigner–Ville ...

Pseudo affine Wigner distributions [PDF]
1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002 We define a new set of tools for time-varying spectral analysis: the pseudo affine Wigner distributions. Based on the affine Wigner distributions of J. and P. Bertrand (1992), these new time-frequency distributions support efficient online operation at the same computational cost as the continuous wavelet transform. Moreover, they take advantage of the
