Memory cost of quantum contextuality with Pauli observables
Stefan Trandafir, Colm Kelleher, Adán Cabello
Classically simulating the quantum contextual correlations produced by sequences of ideal measurements of compatible observables requires the measured system to have an internal me…
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…
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…
