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…
Stabilizer codes can be realized as graph codes
D. Schlingemann
We establish the connection between a recent new construction technique for quantum error correcting codes, based on graphs, and the so-called stabilizer codes: Each stabilizer cod…
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…
Semicausal operations are semilocalizable
T. Eggeling, D. Schlingemann, R. F. Werner
We prove a conjecture by DiVincenzo, which in the terminology of Preskill et al. [quant-ph/0102043] states that ``semicausal operations are semilocalizable''. That is, we show that…
A computable measure of entanglement
G. Vidal, R. F. Werner
We present a measure of entanglement that can be computed effectively for any mixed state of an arbitrary bipartite system. We show that it does not increase under local manipulati…
