Pauli decomposition via the fast Walsh-Hadamard transform [PDF]

open access: yesNew Journal of Physics
The decomposition of a square matrix into a sum of Pauli strings is a classical pre-processing step required to realize many quantum algorithms. Such a decomposition requires significant computational resources for large matrices. We present an exact and

The Cascading Haar Wavelet Algorithm for Computing the Walsh–Hadamard Transform [PDF]

open access: yesIEEE Signal Processing Letters, 2017
We propose a novel algorithm for computing the Walsh-Hadamard Transform (WHT) which consists entirely of Haar wavelet transforms. We prove that the algorithm, which we call the Cascading Haar Wavelet (CHW) algorithm, shares precisely the same serial complexity as the popular divide-and-conquer algorithm for the WHT.

The Sufficient Condition for Ensuring the Reliability of Perception of the Steganographic Message in the Walsh-Hadamard Transform Domain [PDF]

open access: yesProblems of the Regional Energetics, 2022
In view of the high compatibility of the Walsh-Hadamard transform to the architecture of mod-ern computing facilities, it is sensible to use it in methods of steganography and steganalysis.

Efficient Coding of the Embedded Signal in Steganographic Systems with Multiple Access [PDF]

open access: yesProblems of the Regional Energetics, 2021
Today, steganographic systems with multiple access are of considerable importance. In such sys-tems, the orthogonal Walsh-Hadamard transform is most often used for multiplexing and divid-ing channels, which leads to the need for efficient coding of the ...
