Hardy-Bell inequalities and fault-tolerant Hardy paradoxes

Abstract Usually, the verification of Bell nonlocality involves two main approaches: violation of specific inequalities and utilization of no-inequality methods. In this paper, we continue to develop the inequality methods by deducing the so-called ‘Hardy-Bell inequalities (HBIs)’ and ‘fault-tolerant Hardy paradoxes (FTHPs)’ for correlation tensors (CTs) with two inputs and general outcomes. We prove that the HBIs are necessary conditions for a CT to be Bell local and one of the FTHPs is sufficient condition for a CT to be Bell nonlocal. We demonstrate the effectiveness of HBIs in determining the nonlocality of CTs or quantum states when the classical Hardy paradox does not appear or a Bell inequality is not violated. Consequently, our methods can be utilized to explore more correlations having Bell nonlocality. Based on the obtained results, we find a neighborhood of a Hardy nonlocal state, in which all states are all Bell nonlocal.

Quantum Tomography and Verification of Generalized Bell-CHSH Inequalities

V. A. Andreev

It is shown that verification procedure of Bell inequalities consists of three parts. The first stage of verification procedure is consist of measurements of a set of spin correlations. Using them one can reconstruct a density matrix of two‐particle state. It can be done with the help of quantum tomography technique. At the second stage one must construct a generalized Bell inequality corresponding to this state. This inequality must be constructed in two forms: within the framework of the traditional formulation of quantum mechanics and in the frames of a local hidden variables theory. Only after that the results of experimental measurements can be compared with theoretical predictions. It is a third stage of verification.
