Classifying N-Qubit Entanglement via Bell's Inequalities
All the states of N qubits can be classified into N–1 entanglement classes
from 2-entangled to N-entangled (fully entangled) states. Each class of
entangled states is characterized by an entanglement index that depends on
the partition of N. The larger the entanglement index of a state, the more
entangled or the less separable is the state in the sense that a larger
maximal violation of Bell's inequality is attainable for this class of
state. ?2003 The American Physical Society
