 ">The exact quantum chromatic number of Hadamard graphs and their products
 </a>\nby Meenakshi McNamara (Perimeter Institute) as part of Noncommutativ
 e geometry in NYC\n\n\nAbstract\nQuantum chromatic numbers are defined via
  non-local games on classical graphs. Very few exact computations of the q
 uantum chromatic number of graphs are known. In this talk\, we will give a
  proof of the exact quantum chromatic number of Hadamard graphs. As oppose
 d to prior results on this problem\, this approach uses results on conjuga
 cy class graphs which allows us to consider products of Hadamard graphs as
  well. Specifically\, we compute the exact quantum chromatic number of cat
 egorical products of Hadamard graphs.\n\nThroughout this work\, we use sev
 eral results for the quantum chromatic numbers of quantum graphs\, an oper
 ator algebraic generalization of classical graphs that appears in connecti
 on to quantum information theory. In particular\, we also discuss results 
 on products of quantum graphs appearing in joint work with Rolando de Sant
 iago.\n
