论文摘要
对于许多协议，量子策略与其经典反对手相比具有优势，并且这些优势吸引了许多兴趣和应用。著名的例子之一是Clauser-Horne Shimony-Holt（CHSH）游戏，该游戏将Bell的定理〜\ Cite {2}重新推向游戏框架。在CHSH游戏中，两个类似太空的分离玩家，爱丽丝和鲍勃分别分别分配了一个经典的位$ a $和$ b $。然后，根据一些预先验证的策略，他们返回$ x $和$ y $。当$ x \ oplus y = a \ cdot b $时，他们将赢得游戏。在游戏中，如果玩家使用经典策略，最佳成功概率$ w（\ text {chsh}）= 0.75 $。此外，Popescu和Rohrlich指出，在不违反无信号假设的情况下，也可以在更一般的理论中实现完美的成功概率$ 1 $
For many protocols, quantum strategies have advantages compared with their classical counter-partners, and these advantages have attracted many interests and applications. One of the famous examples is the Clauser-Horne-Shimony-Holt (CHSH) game, which recasts Bell's theorem~\cite{2} into the framework of a game. In the CHSH game, two space-like separated players, Alice and Bob are each assigned a classical bit $a$ and $b$ respectively. Then they return bits $x$ and $y$ according to some pre-agreed strategies. They will win the game when $x\oplus y= a\cdot b$. In the game, if the players use the classical strategies, the optimal success probability $w(\text{CHSH})=0.75$.However, if they add some quantum resources, the success probability will increase and up to maximal value $cos^2(π/8)$, which is know as the Tsirelson's bound. Moreover, Popescu and Rohrlich noted that the perfect success probability $1$ can also be achieved in a more general theory without violating the no-signaling assumption
