Two-Qubit Separabilities as Discontinuous Functions of Maximal Concurrence over Spectral Orbits | | Paul B. Slater
; | | Date: |
20 Jun 2008 | | Abstract: | For the real and complex two-qubit systems, we investigate the possibility
that the associated (three-dimensional) eigenvalue-parameterized separability
functions are expressible as one-dimensional functions (s(C)) of the maximal
concurrence over spectral orbits (C in [0,1]). Our numerical estimates, in this
regard, are encouraging, in that they closely reproduce independently-generated
results and conjectures concerning separability probabilities based on the
Hilbert-Schmidt and Bures (minimal monotone) metrics over the two-qubit
systems, and the use of diagonal-entry-parameterized separability functions.
Plots of the real and complex versions of s(C) both exhibit prominent
discontinuities at C=1/2, and, at least, three additional discontinuities (C =
0.204, 0.294, 0.34). Over the interval C in [0.204,0.34], the two fitted
functions s(C) both appear to be linear (except at C =0.294). | | Source: | arXiv, 0806.3294 | | Services: | Forum | Review | PDF | Favorites | |
