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…
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…
Estimating the spectrum of a density operator
M. Keyl, R. F. Werner
Given N quantum systems prepared according to the same density operator ρ, we propose a measurement on the N-fold system which approximately yields the spectrum of ρ. The projectio…
All multipartite Bell correlation inequalities for two dichotomic observables per site
R. F. Werner, M. M. Wolf
We construct a set of 2^(2^n) independent Bell correlation inequalities for n-partite systems with two dichotomic observables each, which is complete in the sense that the inequali…
