- Abstract
Violation of Bell's inequalities for N-particle correlation functions by pure entagled states was discussed. Pure entangled N>2 qubit states were shown to exist that did not violate any Bell inequality for experiments involving two dichotomic observables per local measuring station. Results also showed that Mermin-Ardehali-Belinskii-Klyshko inequalities might not always be optimal for refutation of local realistic description.
