Collective quantum games with Werner-like states

This article studies the collective behaviour of quantum games with Werner-like states, where every player interacts with four partners and four mates. Four two-person game types are scrutinized by allowing the players to adopt the strategy of his best paid mate. Particular attention is paid in the study to the effect of variable degree of entanglement and fidelity to the quantum model on Nash equilibrium strategy pairs. (C) 2018 Elsevier B.V.
