Room correction: The talk will actually take place at IFW, D44. Cheers! Manuel ---------- Forwarded message ---------- From: Forster Manuel <forstema@gmail.com> Date: 2008/11/17 Subject: abstract of talk, research day, 19.11.2008 To: itp-quantumseminare@phys.ethz.ch Hi, The next talk will take place 5 pm at IFW E42. The talk will be held by Severin and Manuel about non-locality distillation, following a recent paper: http://arxiv.org/abs/0809.3173 Abstract: "Quantum non-locality -- the fact that the behavior under measurements of (spatially separated) parts of a system can have a correlation unexplainable by shared classical information -- has proven to be a helpful resource in cryptography and communication complexity. Since non-locality is more useful if it is stronger, it is a natural question whether it can be distilled, i.e., whether strong non-local correlations can be obtained from weaker ones. We answer this question with *yes* by giving the first known examples of distillable non-locality." The talk will give a very basic introduction into non-signaling systems and non-locality distillation and explain a recently found result. Best regards. Manuel
