Canonical coset parametrization and the Bures metric of the three-level quantum systems

Abstract

An explicit parametrization for the state space of an n-level density matrix is given. The parametrization is based on the canonical coset decomposition of unitary matrices. We also compute, explicitly, the Bures metric tensor over the state space of two- and three-level quantum systems.

Coset parameterization of density matrices

Seyed Javad Akhtarshenas

We give an explicit parameterization for the state space of an n -level density matrix. The parameterization is based on the canonical coset decomposition of unitary matrices. As an application, we also calculate explicitly the Bures metric tensor over the state space of two-level quantum system.

Calculation of the unitary part of the Bures measure for N-level quantum systems

Renan Cabrera, Herschel Rabitz

We use the canonical coset parameterization and provide a formula with the unitary part of the Bures measure for non-degenerate systems in terms of the product of even Euclidean balls. This formula is shown to be consistent with the sampling of random states through the generation of random unitary matrices.

Explicit formulae for the Bures metric

Jochen Dittmann

The aim of this paper is to derive explicit formulae for the computation of the Riemannian Bures metric g on the manifold of (finite-dimensional) nonsingular density matrices . This Riemannian metric introduced by Uhlmann generalizes the Fubini-Study metric to mixed states and is the infinitesimal version of the Bures distance. Several formulae are known for computing the Bures metric in low dimensions. The formulae presented in this paper allow for computing in finite dimensions without any diagonalization procedures. The first equations we give are, essentially, of the form , where is a matrix of invariants of . A further formula, , is adapted to the local orthogonal decomposition at generic points.
