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
