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…
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 new heuristic approach for contextuality degree estimates and its four- to six-qubit portrayals
Axel Muller, Metod Saniga, Alain Giorgetti +2
We introduce and describe a new heuristic method for finding an upper bound on the degree of contextuality and the corresponding unsatisfied part of a quantum contextual configurat…
Exploiting Finite Geometries for Better Quantum Advantages in Mermin-Like Games
Colm Kelleher, Frédéric Holweck, Péter Lévay
Quantum games embody non-intuitive consequences of quantum phenomena, such as entanglement and contextuality. The Mermin-Peres game is a simple example, demonstrating how two playe…
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…
Two new non-equivalent three-qubit CHSH games
Hamza Jaffali, Frédéric Holweck
In this paper, we generalize to three players the well-known CHSH quantum game. To do so, we consider all possible 3 variables Boolean functions and search among them which ones co…
Implementing 2-qubit pseudo-telepathy games on noisy intermediate scale quantum computers
Colm Kelleher, Mohammad Roomy, Frédéric Holweck
It is known that Mermin-Peres like proofs of quantum contextuality can furnish non-local games with a guaranteed quantum strategy, when classically no such guarantee can exist. Thi…
