Hi all,
This Wednesday, August 4, we will have two visitors from Geneva University,
Jean-Daniel Bancal and Denis Rosset.
They will present to us one of their subjects of interest, namely bi- and
multi-locality. I hope that many of you can make it to their presentation.
Best regards,
Stefan

Title: Multi-nonlocality : how can we characterize the quantum correlations
of entangled independent sources ?
Abstract : We consider a three-party experiment with two independent
quantum sources (as in entanglement swapping). In this scenario, we show
that the local polytope is further restricted to a non-convex set, whose
boundaries are described by non-linear inequalities. In particular, we exhibit
correlations that a classical model can reproduce with a maximal visibility
of 50% (an improvement of 20% over the CHSH case).
