dc.description.abstract | We derive a Bell inequality for testing violation of local realism. Quantum nonlocality of several four-qubit states is investigated. These include the Greenberger-Zeilinger-Horne (GHZ) state, W state, linear cluster state, and the state | χ that has recently been proposed in. The Bell inequality is optimally violated by | χ but not violated by the GHZ state. The linear cluster state also violates the Bell inequality though not optimally. The state | χ can thus be discriminated from the linear cluster state by using the inequality. Different aspects of four-partite entanglement are also studied by considering the usefulness of a family of four-qubit mixed states as resources for two-qubit teleportation. Our results generalize those in. © 2007 The American Physical Society. | |
