Maximally Entangled State in Pseudo-Telepathy Games

A pseudo-telepathy game is a non-local game which can be won with probability one using quantum strategies but not using classical ones. Our central question is whether there exist two-party pseudo-telepathy games which cannot be won with probability one using a maximally entangled state. Towards answering this question, we develop conditions under which maximally entangled state suffices. Our main result shows that for any game \(G\), there exists a game \(\tilde{G}\) such that \(G\) admits a perfect strategy using a maximally entangled state if and only if \(\tilde{G}\) admits some perfect finite-dimensional quantum strategy.
