2nd QI-Movie Evening
by Galliard Viktor 17 Mar '08

17 Mar '08

Hi all! After the successful starting event a few weeks ago w'll have the successor tomorrow. After the movie we might move to Safari or somewhere else... We meet at 730PM at IFW E-Stock. You might bring you own food or we order Pizza before the movie (or shop up stuffed :-). If you want bring your favourite movies with you and we try to democratically elect a suitable movie. btw. see attached pics from the last event. btw2. rumors say that all members of Stefan will attend the event! See you tomorrow Viktor

tomorrow's talk
by Roger Colbeck 03 Mar '08

03 Mar '08

Hi all, Tomorrow's talk will be by Viktor at 5pm in the Pauli Room. See you there, Roger Title: Simulating Quantum Correlations with finite Communication (RT07) It is well known that measurements on quantum states may reveal some behaviour which cannot be produced classically. The last 15 years people have tried to quantify this 'non-local part' using several information theoretic primitives such as NL-boxes or classical bits used for communication. In 2003 Bacon and Toner could show that 1 classical bit of one-way communication suffices to simulate the EPR-pair setup for arbitrary 2-outcome measurements. In 2007, Regev and Toner could show that 2 classical bits of communication suffice to simulate quantum correlations on a (known) bi-partite state of dimension d x d with 2-outcome measurements. Surprisingly, only 2 bits of communication is needed (independent of the dimension d). Nevertheless, even though quantum correlations $\alpha \beta$ can be simulated, their protocol does not yield correct marginals. Not much is known beyond these cases. In this talk we will give a brief sketch of the techniques used by Regev and Toner.

Research Day plus Movie and Jazz
by Roger Colbeck 21 Feb '08

21 Feb '08

Hi all, For next Tuesday's talk we have a visitor, Andre Methot. The talk will be at 5pm in the Pauli room (title and abstract below). Also, Viktor is arranging a post-talk Movie and Jazz evening (see his message below). Cheers, Roger Title: Entanglement simulations and channels. Abstract: We will study the different entanglement simulation models: their structure, their motivation and the links that brings them all together. We will then introduce a novel idea. Linking them to classical and quantum channels. -------- Original Message -------- Subject: Research Day After Hour - Movie and Jazz Date: Wed, 20 Feb 2008 20:17:08 +0100 From: Galliard Viktor <viktor.galliard(a)inf.ethz.ch> To: <itp-quantumseminare-bounces(a)phys.ethz.ch>, <qi(a)lists.inf.ethz.ch> Hi all. After 1 1/2 years (!!) Stefans QI group (hopefully) managed to fix a date and movie for the first (official) QI Movie Evening. This will take place after the Research Day @ Hoenggerberg next Tuesday. Some of us will continue socializing at a 'cosy' Jazz concert @ Helsinki. I look forward for some people to join. Cheers, Viktor
