Lewenstein-Sanpera decomposition of a generic 2x2 density matrix by using Wootters's basis
S. J. Akhtarshenas, M. A. Jafarizadeh
The Lewenstein-Sanpera decomposition for a generic two-qubit density matrix is obtained by using Wootters's basis. It is shown that the average concurrence of the decomposition is…
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…
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…
Robustness of Entanglement for Bell Decomposable States
S. J. Akhtarshenas, M. A. Jafarizadeh
We propose a simple geometrical approach for finding the robustness of entanglement for Bell decomposable states of 2 otimes 2 quantum systems. It is shown that the robustness of e…
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,…
