Entanglement versus Bell violations and their behaviour under local filtering operations
Frank Verstraete, Michael M. Wolf
We discuss the relations between the violation of the CHSH Bell inequality for systems of two qubits on the one side and entanglement of formation, local filtering operations, and…
Violation of Bell's inequalities implies distillability for N qubits
A. Acin, V. Scarani, M. M. Wolf
We consider quantum systems composed of qubits, and the family of all Bell's correlation inequalities for two two-valued measurements per site. We show that if a -qubit stat…
Can spectral and local information decide separability?
Karl G. H. Vollbrecht, Michael M. Wolf
We discuss the discriminating power of separability criteria, which are based on the spectrum of a quantum state and its reductions. Common examples are entropic inequalities utili…
Bell inequalities and Entanglement
Reinhard F. Werner, Michael M. Wolf
We discuss general Bell inequalities for bipartite and multipartite systems, emphasizing the connection with convex geometry on the mathematical side, and the communication aspects…
Distillability via protocols respecting the positivity of partial transpose
Tilo Eggeling, Karl Gerd H. Vollbrecht, Reinhard F. Werner +1
We show that all quantum states that do not have a positive partial transpose are distillable via channels, which preserve the positivity of the partial transpose. The question whe…
Comment on: Necessary and sufficient condition of separability of any system
T. Eggeling, K. G. H. Vollbrecht, M. M. Wolf
In a recent paper (quant-ph/0102133) Chen, Liang, Li and Huang suggest a necessary and sufficient separability criterion, which is supposedly practical in judging the separability…
