A Quantum Algorithm For Computing Contextuality Bounds
Colm Kelleher, Frédéric Holweck
Quantum contextuality is a limitation on deterministic hidden variable models, testable in measurement scenarios where outcomes differ under quantum or classical descriptions due t…

Empirical Demonstration of Quantum Contextuality on NISQ Computers
Colm Kelleher, Frédéric Holweck
We present definitive violations of non-contextual hidden variable bounds in the latest generation of IBM noisy intermediate-scale quantum computers (NISQ). These violations are ba…

Four-Qubit CHSH Games
Joaquim Jusseau, Hamza Jaffali, Frédéric Holweck
In this paper, the CHSH quantum game is extended to four players. This is achieved by exploring all possible 4-variable Boolean functions to identify those that yield a game scenar…
