Dear all, On Monday next week, Oleg Szehr will present his semester project Time and Location: Monday, August 30, 11.00, HIT K51 Title: Quantum coding via the decoupling approach Abstract: The talk focuses on the decoupling approach to quantum coding. The aim is to show a strong quantum coding theorem, which arises from an application of the decoupling theorem. A rough overview of the technical proofs of i) The Decouping Theorem, ii) The smoothed Decoupling Theorem, iii) The quantum Coding Theorem, is given. I hope to see many of you there. Best wishes Matthias.

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 ________________________________________________________________ Presentation by Jean-Daniel Bancal and Denis Rosset, Group of Applied Physics, Geneva University. Wed., August 4, 14:00, CAB G 59 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). ________________________________________________________________
