WebWhat Tsirelson observed is that the Grothendieck constant could be interpreted as an upper bound for the “deviation” in the (generalized) Bell inequalities. Moreover, there would be no deviation if the Grothendieck constant was equal to 1 ! This corresponds to an experiment with essentially two independent (because very distant) observers ...
