Testing locality or noncontextuality with lowest moments

The quest for fundamental test of quantum mechanics is an ongoing effort. We are addressing the question of what are the lowest possible moments to prove quantum nonlocality and noncontextuality without any further assumption – in particular without the often assumed dichotomy. We first show that second order correlations can always be explained by a classical noncontextual local hidden variabl...

Graph-theoretic approach to quantum correlations.

Correlations in Bell and noncontextuality inequalities can be expressed as a positive linear combination of probabilities of events. Exclusive events can be represented as adjacent vertices of a graph, so correlations can be associated to a subgraph. We show that the maximum value of the correlations for classical, quantum, and more general theories is the independence number, the Lovász number...

Optimal inequalities for state-independent contextuality.

Contextuality is a natural generalization of nonlocality which does not need composite systems or spacelike separation and offers a wider spectrum of interesting phenomena. Most notably, in quantum mechanics there exist scenarios where the contextual behavior is independent of the quantum state. We show that the quest for an optimal inequality separating quantum from classical noncontextual cor...

From the Kochen-Specker theorem to noncontextuality inequalities without assuming determinism.

The Kochen-Specker theorem demonstrates that it is not possible to reproduce the predictions of quantum theory in terms of a hidden variable model where the hidden variables assign a value to every projector deterministically and noncontextually. A noncontextual value assignment to a projector is one that does not depend on which other projectors-the context-are measured together with it. Using...

Parity Oblivious d-Level Random Access Codes and Class of Noncontextuality Inequalities

One of the fundamental results in quantum foundations is the Kochen-Specker no-go theorem. For the quantum theory, the no-go theorem excludes the possibility of a class of hidden variable models where value attribution is context independent. Recently, the notion of contextuality has been generalized for different operational procedures and it has been shown that preparation contextuality of mi...
