Quantum advantages in classically defined tasks
arXiv:0710.1721 · doi:10.1103/PhysRevA.77.052310
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.
