Bures/statistical distinguishability probabilities of triseparable and biseparable Eggeling-Werner States | | Paul B. Slater
; | | Date: |
6 Jun 2003 | | Subject: | quant-ph | | Affiliation: | University of California | | Abstract: | In a number of previous studies, we have investigated the use of the volume element of the Bures (minimal monotone) metric -- identically, one-fourth of the statistical distinguishability (SD) metric -- as a natural measure over the (n^2-1)-dimensional convex set of n x n density matrices. This has led us for the cases n = 4 and 6 to estimates of the prior (Bures/SD) probabilities that qubit-qubit and qubit-qutrit pairs are separable. Here, we extend this work from such bipartite systems to the tripartite "laboratory’’ quantum systems possessing U x U x U symmetry recently constructed by Eggeling and Werner (Phys. Rev. A 63 [2001], 042324). We derive the associated SD metric tensors for the three-qubit and three-qutrit cases, and then obtain estimates of the various related Bures/SD probabilities using Monte Carlo methods. | | Source: | arXiv, quant-ph/0306053 | | Services: | Forum | Review | PDF | Favorites | |
