Almost Quantum Correlations are Inconsistent with Specker's Principle
Tomáš Gonda, Ravi Kunjwal, David Schmid +2
Ernst Specker considered a particular feature of quantum theory to be especially fundamental, namely that pairwise joint measurability of sharp measurements implies their global jo…
All the noncontextuality inequalities for arbitrary prepare-and-measure experiments with respect to any fixed sets of operational equivalences
David Schmid, Robert W. Spekkens, Elie Wolfe
Within the framework of generalized noncontextuality, we introduce a general technique for systematically deriving noncontextuality inequalities for any experiment involving finite…
Geometry of the set of quantum correlations
Koon Tong Goh, Jędrzej Kaniewski, Elie Wolfe +5
It is well known that correlations predicted by quantum mechanics cannot be explained by any classical (local-realistic) theory. The relative strength of quantum and classical corr…
Universal bound on the cardinality of local hidden variables in networks
Denis Rosset, Nicolas Gisin, Elie Wolfe
We present an algebraic description of the sets of local correlations in arbitrary networks, when the parties have finite inputs and outputs. We consider networks generalizing the…
Causal Compatibility Inequalities Admitting Quantum Violations in the Triangle Structure
Thomas C. Fraser, Elie Wolfe
It has long been recognized that certain quantum correlations are incompatible with particular assumption about classical causal structure. Given a causal structure of unknown clas…
The Inflation Technique Completely Solves the Causal Compatibility Problem
Miguel Navascues, Elie Wolfe
The causal compatibility question asks whether a given causal structure graph -- possibly involving latent variables -- constitutes a genuinely plausible causal explanation for a g…
Deriving robust noncontextuality inequalities from algebraic proofs of the Kochen-Specker theorem: the Peres-Mermin square
Anirudh Krishna, Robert W. Spekkens, Elie Wolfe
When a measurement is compatible with each of two other measurements that are incompatible with one another, these define distinct contexts for the given measurement. The Kochen-Sp…
Is error detection helpful on IBM 5Q chips ?
Christophe Vuillot
This paper reports on experiments realized on several IBM 5Q chips which show evidence for the advantage of using error detection and fault-tolerant design of quantum circuits. We…
Multipartite Composition of Contextuality Scenarios
Ana Belén Sainz, Elie Wolfe
Contextuality is a particular quantum phenomenon that has no analogue in classical probability theory. Given two independent systems, a natural question is how to represent such a…
