Constructing a Set of Kronecker-Pauli Matrices

Christian Rakotonirina

In quantum physics, the choice of basis is crucial for formulation. The generalization of the Pauli matrices via Kronecker product, called Kronecker-Pauli matrices, is typically restricted to for $2^n$ dimensional systems. This paper explores extending this generalization to $N$ -dimensional systems, where $N$ is a prime integer, in order to construct $N\times N$ -Kronecker-Pauli matrices. We begin by examining the specific cases of $3\times 3$ and $5\times 5$ Kronecker-Pauli matrices, with the goal of the purpose constructing a set of $N\times N$ -Kronecker-Pauli matrices for any prime integer $N$ .In quantum physics, the choice of basis is crucial for formulation.

A Relation Between the Chrestenson Operator, Weyl Operator Basis, and Kronecker-Pauli Operator Basis

Mickaya A. Razanaparany, Christian Rakotonirina

Within the framework of quantum theory, we review the Chrestenson operator, the Weyl operator basis, and the Kronecker-Pauli operator basis in $d$ -dimensional Hilbert spaces using Dirac notation, where $d$ is a prime integer strictly greater than 2. We establish a new algebraic relation connecting these operators and present the cases $d=3$ and $d=5$ as illustrative examples.Within the framework of quantum theory, we review the Chrestenson operator, the Weyl operator basis, and the Kronecker-Pauli operator basis in $d$-dimensional Hilbert spaces using Dirac notation, where $d$ is a prime integer strictly greater than 2.
