Yes, the (very nice) game you described gives a separation between classical and quantum mechanics. However, there is a strategy in real quantum mechanics which also achieves a 100% winrate for the players (you just need higher dimensional Hilbert spaces for each player). Instead of preparing |+++> + |–-->, you prepare the state (|+++>|x> + |–-->|x>) Here, |x> = |000>-|011>-|101>-|110>, and one qubit is sent to each player. That is, you give each of Alice, Bob and Charlie an extra qubit. They can now measure in the computational basis on both qubits. And in the betrayal round two of the…
