Robustness of entanglement for two qubit density matrix
S. J. Akhtarshenas, M. A. Jafarizadeh
By considering the decomposition of a generic two qubit density matrix presented by Wootters [W. K. Wootters, Phys. Rev. Lett. {\bf 80} 2245 (1998)], the robustness of entanglement…
Lewenstein-Sanpera Decomposition for Systems
S. J. Akhtarshenas, M. A. Jafarizadeh
As it is well known, every bipartite density matrix can be obtained from Bell decomposable states via local quantum operations and classical communications (LQCC). Usi…
Lewenstein-Sanpera Decomposition for Iso-concurrence Decomposable States
S. J. Akhtarshenas, M. A. Jafarizadeh
We obtain Lewenstein-Sanpera decomposition of iso-concurrence decomposable states of quantum systems. It is shown that in these systems average concurrence of the deco…
Remarks on the Cross Norm Criterion for Separability
S. J. Akhtarshenas, M. A. Jafarizadeh
Recently in Reference [ quant-ph/0202121] a computational criterion of separability induced by greatest cross norm is proposed by Rudolph. There, Rudolph conjectured that the new c…
Concurrence as a Relative Entropy with Hilbert-Schmidt Distance in Bell Decomposable States
S. J. Akhtarshenas, M. A. Jafarizadeh
Hilbert-Schmidt distance reduces to Euclidean distance in Bell decomposable states. Based on this, entanglement of these states are obtained according to the protocol proposed in R…
Lewenstein-Sanpera decomposition For Bell Decomposable
S. J. Akhtarshenas, M. A. Jafarizadeh
We propose a simple geometrical approach for finding the Lewenstein-Sanpera decomposition of Bell decomposable states of 2 otimes 2 quantum systems. We show that in these systems,…
