Dear all,

We will have the fourth seminar in the mathematics seminar series
tomorrow. The speaker is Jitendra Prakash from University of Waterloo,
Canada. Details are below:

Title: Tsirelson's problems and non-closure of the set of quantum correlations

Date/Time: 24th September, Monday, 4:00PM - 5:00PM

Venue: A006, New Academic Building

Abstract

We consider a bipartite system with two observers, Alice and Bob, who
are performing measurements in their labs. There are two models of
quantum mechanics which describe the joint lab of Alice and Bob ---
the quantum model and the commuting quantum model. Tsirelson's
original question asked whether these two models were essentially the
same. We show that these two models are different for bipartite
systems with five quantum experiments and binary outcomes for each
experiment, by using the notion of correlation functions of graphs.
