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…
Hierarchy of chaotic maps with an invariant measure and their compositions
M. A. Jafarizadeh, S. Behnia
We give a hierarchy of many-parameter families of maps of the interval [0,1] with an invariant measure and using the measure, we calculate Kolmogorov--Sinai entropy of these maps a…
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…
Hierarchy of one and many-parameter families of elliptic chaotic maps of cn and sn types
M. A. Jafarizadeh, S. Behnia
We present hierarchy of one and many-parameter families of elliptic chaotic maps of cn and sn types at the interval [0,1]. It is proved that for small values of k the parameter of…
Hierarchy of Chaotic maps with an invariant measure and their coupling
M. A. Jafarizadeh, S. Behnia
Hierarchy of one-parameter families of chaotic maps with an invariant measure have been introduced, where their appropriate coupling has lead to the generation of some coupled chao…
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,…
