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…
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…
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…
