Strenghtened Bell inequalities for orthogonal spin directions

Research output: Contribution to journal › Article › Academic › peer-review

Abstract

We provide bounds on correlations of locally orthogonal observables in two-qubit separable states. These bounds strengthen the Bell inequality and improve upon some alternative entanglement criteria. They provide necessary and sufficient criteria for separability of pure states and test the correlations allowed by local hidden variable models against those allowed by separable quantum states.
