Abstract
All the states of qubits can be classified into entanglement classes from 2-entangled to -entangled (fully entangled) states. Each class of entangled states is characterized by an entanglement index that depends on the partition of . 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.
