H-DES: a Quantum-Classical Hybrid Differential Equation Solver
Hamza Jaffali, Jonas Bastos de Araujo, Nadia Milazzo +6
In this article, we introduce an original hybrid quantum-classical algorithm based on a variational quantum algorithm for solving systems of differential equations. The algorithm r…
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…
Hexagons govern three-qubit contextuality
Metod Saniga, Frédéric Holweck, Colm Kelleher +3
Split Cayley hexagons of order two are distinguished finite geometries living in the three-qubit symplectic polar space in two different forms, called classical and skew. Although…
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…
