非局部性与利益冲突博弈

Nonlocality and conflicting interest games

摘要:

非定域性使双方赢得特定游戏的概率严格高于任何经典理论所允许的。然而,所有已知的这样的例子都考虑了双方有共同利益的博弈,因为他们共同赢得或输掉了博弈。我们在这里要问的主要问题是,量子力学的非定域特性是否能在双方利益冲突的情况下提供优势。我们通过一个简单的利益冲突博弈来肯定地回答这个问题,在这个博弈中,量子策略优于经典策略。此外,我们表明,我们的游戏有一个公平的量子均衡,更高的回报,为双方球员比任何公平的经典均衡。最后,我们使用商业纠缠光子源进行游戏,并在实验上证明了量子优势。

英文摘要:

Nonlocality enables two parties to win specific games with probabilities strictly higher than allowed by any classical theory. Nevertheless, all known such examples consider games where the two parties have a common interest, since they jointly win or lose the game. The main question we ask here is whether the nonlocal feature of quantum mechanics can offer an advantage in a scenario where the two parties have conflicting interests. We answer this in the affirmative by presenting a simple conflicting interest game, where quantum strategies outperform classical ones. Moreover, we show that our game has a fair quantum equilibrium with higher payoffs for both players than in any fair classical equilibrium. Finally, we play the game using a commercial entangled photon source and demonstrate experimentally the quantum advantage.
