Abstract
The N-qubit states of the W class, for N>10, lead to more robust (against noise admixture) violations of local realism, than the states of the GHZ class. These violations are most pronounced for correlations for a pair of qubits, conditioned on specific measurement results for the remaining N-2 qubits.
