Quantum advantages in classically defined tasks

TL;DR

This paper demonstrates that quantum teams can outperform classical teams in certain spatially separated games by leveraging EPR correlations, including a novel example of a local game with quantum advantage.

Contribution

It introduces a new class of classically defined games where quantum strategies provide a definitive advantage, even in single-location scenarios.

Findings

Quantum teams outperform classical teams in spatially separated games.

Quantum advantage demonstrated in a local game scenario.

EPR correlations enable superior strategies for quantum teams.

Abstract

We analyze classically defined games for which a quantum team has an advantage over any classical team. The quantum team has a clear advantage in games in which the players of each team are separated in space and the quantum team can use unusually strong correlations of the Einstein-Podolsky-Rosen (EPR) type. We present an example of a classically defined game played at one location for which quantum players have a real advantage.
