Entanglement monotones and maximally entangled states in multipartite qubit systems
Andreas Osterloh, Jens Siewert
We present a method to construct entanglement measures for pure states of multipartite qubit systems. The key element of our approach is an antilinear operator that we call {\em co…
Constructing N-qubit entanglement monotones from anti-linear operators
Andreas Osterloh, Jens Siewert
We present a method to construct entanglement measures for pure states of multipartite qubit systems. The key element of our approach is an antilinear operator that we call {\em co…
Bell Inequalities for Graph States
Otfried Guehne, Geza Toth, Philipp Hyllus +1
We investigate the non-local properties of graph states. To this aim, we derive a family of Bell inequalities which require three measurement settings for each party and are maxima…
Detecting Genuine Multipartite Entanglement with Two Local Measurements
Geza Toth, Otfried Guehne
We present entanglement witness operators for detecting genuine multipartite entanglement. These witnesses are robust against noise and require only two local measurement settings…
Parametric Oscillation with Squeezed Vacuum Reservoirs
Alem Mebrahtu
Employing the quantum Hamiltonian describing the interaction of two-mode light (signal-idler modes) generated by a nondegenerate parametric oscillator (NDPO) with two uncorrelated…
Simplifying Schmidt number witnesses via higher-dimensional embeddings
Florian Hulpke, Dagmar Bruss, Maciej Lewenstein +1
We apply the generalised concept of witness operators to arbitrary convex sets, and review the criteria for the optimisation of these general witnesses. We then define an embedding…
