Abstract:In previous studies, we have explored the ansatz that the volume elements of the Bures metrics over quantum systems might serve as prior distributions, in analogy with the (classical) Bayesian role of the volume elements (“Jeffreys' priors”) of Fisher information metrics. Continuing this work, we obtain exact Bures prior probabilities that the members of certain low-dimensional subsets of the fifteen-dimensional convex set of density matrices are separable or classically correlated…

Here, making use of a newly-developed (Euler angle) parameterization of the 4 × 4 density matrices of Tilma, Byrd and Sudarshan, the analysis is extended to the complete 15-dimensional convex set (C) of arbitrarily paired qubits and conjecture that this is but an approximation to the exact Bures/SD probability of separability.

A priori probability that a qubit–qutrit pair is separable

We extend to arbitrarily coupled pairs of qubits (two-state quantum systems) and qutrits (three-state quantum systems) our earlier study (Slater 2002 Quantum Inf. Process. 1 387), which was concerned

Bures and Hilbert–Schmidt 2 × 2 determinantal moments

We seek to gain insight into the nature of the determinantal moments 〈|ρPT|n|ρ|k〉Bures of generic (nine-dimensional) two-rebit and (fifteen-dimensional) two-qubit systems (ρ), PT denoting partial

Dyson indices and Hilbert–Schmidt separability functions and probabilities

A confluence of numerical and theoretical results leads us to conjecture that the Hilbert–Schmidt separability probabilities of the 15- and 9-dimensional convex sets of complex and real two-qubit

A quasirandom methodology is employed, recently developed by Martin Roberts, to estimate the separability probabilities, with respect to the Bures (minimal monotone/statistical distinguishability) measure, of generic two-qubit and two-rebit states of Hilbert-Schmidt and Bures qubit-qudit positive-partial-transpose (PPT)-probabilities.

Geometric approach to the distribution of quantum states in bipartite physical systems

Any set of pure states living in a given Hilbert space possesses a natural and unique metric—the Haar measure—on the group U(N) of unitary matrices. However, there is no specific measure induced on

A concise formula for generalized two-qubit Hilbert–Schmidt separability probabilities

We report major advances in the research program initiated in ‘Moment-based evidence for simple rational-valued Hilbert–Schmidt generic 2 × 2 separability probabilities’ (Slater and Dunkl 2012 J.

Advances in delimiting the Hilbert–Schmidt separability probability of real two-qubit systems

We seek to derive the probability—expressed in terms of the Hilbert–Schmidt (Euclidean or flat) metric—that a generic (nine-dimensional) real two-qubit system is separable, by implementing the

Volume Elements of Monotone Metrics on the n x n Density Matrices as Densities-of-States for Thermodynamic Purposes. II

We derive explicit expressions for the volume elements of both the minimal and maximal monotone metrics over the (n^{2} - 1)-dimensional convex set of n x n density matrices for the cases n = 3 and

Nonlocal Properties of Two-Qubit Gates and Mixed States, and the Optimization of Quantum Computations

It is proved that one of two mixed states can be transformed into the other by single-qubit operations if and only if these states have equal values of all 18 invariants, which provides a complete description of nonlocal properties.

Physics from Fisher Information: A Unification

This book defines and develops a unifying principle of physics, that of 'extreme physical information'. The information in question is, perhaps surprisingly, not Shannon or Boltzmann entropy but,

Density Matrices and Geometric Phases for n-state Systems

An explicit parameterization is given for the density matrices for $n$-state systems. The geometry of the space of pure and mixed states and the entropy of the $n$-state system is discussed.
