Bures Measures over the Spaces of Two and Three-Dimensional Density Matrices

چکیده
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 this methodology can be put. One that has received particular attention is in the construction of certain distinguished (Bures) measures on the (n2 − 1)-dimensional convex sets of n× n density matrices.

Statistical properties of random density matrices
Statistical properties of ensembles of random density matrices are investigated. We compute traces and von Neumann entropies averaged over ensembles of random density matrices distributed according to the Bures measure. The eigenvalues of the random density matrices are analysed: we derive the eigenvalue distribution for the Bures ensemble which is shown to be broader then the quarter-circle di...

In this article we review an algebraic definition of the gyrogroup and a simplified version of the gyrovector space with two fundamental examples on the open ball of finite-dimensional Euclidean spaces, which are the Einstein and M"{o}bius gyrovector spaces. We introduce the structure of gyrovector space and the gyroline on the open convex cone of positive definite matrices and explore its...
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 کاملCanonical 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.
