 When a measurement is made on the electron, it collapses to one of the base states, thus conveying the strategy used by the player.The set of qubits which are initially provided to each of the players (to be used to convey their choice of strategy) may be entangled.For instance, an entangled pair of qubits implies that an operation performed on one of the qubits, affects the other qubit as well, thus altering the expected pay-offs of the game.
