AI 中文总结
研究贝叶斯游戏中关联对玩家的影响，发现可分离量子态能创造优于经典关联均衡的新量子均衡，证明非经典关联是资源，让游戏中的量子优势更易实现。
AI 中文摘要
贝叶斯游戏，也称为不完全信息博弈，是一个通过博弈均衡来探索关联对一组独立主体（玩家）影响的富有成果的领域。此前人们认识到玩家之间共享的量子态与经典关联相比可导致新的有益均衡。此前这种效应的例子需要纠缠态，本文表明即使是可分离态也能在博弈中创造新的、真正的量子均衡，且相对于所有经典关联均衡更具优势。这表明纠缠之外的非经典关联确实是一种资源，使游戏中的量子优势更接近实现。
英文摘要
Bayesian games, also known as games of incomplete information, are a fruitful arena for exploring the impact of correlations on a set of independent agents (players) via the game equilibria to which they give rise. It was realised some time ago that quantum states shared between the players can lead to new and beneficial equilibria, compared to classical correlation. While until now examples of this effect required an entangled state, here we show that even separable states can create new, genuinely quantum equilibria in games, that are advantageous with respect to all classically correlated equilibria. This shows that non-classical correlations beyond entanglement are indeed a resource, even in otherwise entirely classical situations. Our result brings quantum advantage in games significantly closer to possible realisation.
