Constructing a Set of Kronecker–Pauli Matrices
Christian Rakotonirina
Abstract
In quantum physics, the choice of basis is crucial for formulation. The generalization of the Pauli matrices via the Kronecker product, known as Pauli strings, is typically restricted to 2 n ‐dimensional systems. This paper explores extending this generalization to n ‐dimensional systems, where n is an integer, n > 2, to construct n × n ‐Kronecker–Pauli matrices. We establish a method for constructing a set of Kronecker–Pauli matrices for any dimension by examining the method for constructing the specific cases of 3 × 3 and 5 × 5 Kronecker–Pauli matrices. Another possible method for constructing a set of Kronecker–Pauli matrices, by using the Weyl operators, is discussed.
