Classifying N-qubit Entanglement via Bell's Inequalities
Sixia Yu, Zeng-Bing Chen, Jian-Wei Pan, Yong-De Zhang
abstract: 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 an 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.
