Canonical Coset Parameterization and the Bures Metric of the Three-level Quantum Systems
An explicit parameterization for the state space of an n-level density matrix is given. The parameterization is based on the canonical coset decomposition of unitary matrices. We also compute, explicitly, the Bures metric tensor over the state space of twoand three-level quantum systems.
متن کاملA ug 1 99 8 Note on Explicit Formulae for the Bures Metric
The aim of this paper is to derive explicit formulae for the Riemannian Bures metric g on the manifold D of (finite dimensional) nondegenerate density matrices ̺. The computation of the Bures metric using these equations does not require any diagonalization procedure. The first equations we give are, essentially , of the form g = a ij Tr d̺ ̺ i−1 d̺ ̺ j−1 , where a i,j is a matrix of invari-ants of ̺...
متن کاملBures Measures over the Spaces of Two and Three-Dimensional Density Matrices
Due to considerable recent interest in the use of density matrices for a wide variety of purposes, including quantum computation, we present a general method for their parameterizations in terms of Euler angles. We assert that this is of more fundamental importance than (as several people have remarked to us) “just another parameterization of the density matrix.” There are several uses to which...
متن کاملBures Metrics for Certain High-Dimensional Quantum Systems
Hübner’s formula for the Bures (statistical distance) metric is applied to both a one-parameter and a two-parameter series (n = 2, . . . , 7) of sets of 2 × 2 density matrices. In the doublyparameterized series, the sets are comprised of the n-fold tensor products — corresponding to n independent, identical quantum systems — of the 2 × 2 density matrices with real entries. The Gaussian curvatur...
متن کاملBures volume of the set of mixed quantum states
We compute the volume of the (N2 − 1)-dimensional set MN of density matrices of size N with respect to the Bures measure and show that it is equal to that of an (N2 − 1)-dimensional hyper-hemisphere of radius 1/2. For N = 2 we obtain the volume of the Uhlmann hemisphere, 2 S 3 ⊂ R. We find also the area of the boundary of the set MN and obtain analogous results for the smaller set of all real d...
