Hi, Next week's seminar talk will be by Matthias Christandl: Tuesday, Dec. 14, 16:30 at HIT J 52. Best regards, Stefan _____________________________________________________________ Title: Faithful Squashed Entanglement Abstract: Squashed entanglement is a measure for entanglement. Indeed it turns out to be "faithful", that is strictly positive on entangled states and zero on separable states. Rather than explaining the algorithm for separability that follows from the faithfulness (see Theory Colloquium), I hope to give you an idea about the strange mix of techniques that is used to prove the result. ______________________________________________________________
