Title

Bell-type inequalities for non-local resources

Authors
Published in Journal of Mathematical Physics. 2006, vol. 47, no. 11, p. 112101
Abstract We present bipartite Bell-type inequalities which allow the two partners to use some non-local resource. Such inequality can only be violated if the parties use a resource which is more non-local than the one permitted by the inequality. We introduce a family of N-inputs non-local machines, which are generalizations of the well-known PR-box. Then we construct Bell-type inequalities that cannot be violated by strategies that use one these new machines. Finally we discuss implications for the simulation of quantum states.
