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…
