摘要:

理解量子纠缠作为一种资源在各种信息处理任务中所扮演的角色是量子信息理论的关键目标之一。本文提出了一种新的研究量子纠缠的视角:节点间无通信的函数分布式计算。为了使这种方法形式化,我们提出了身份游戏。令人惊讶的是,尽管没有信号,我们得到的非局部量子策略击败经典的在赢得概率的身份游戏起源于某些二分和多分功能。此外,我们表明,对于大多数的功能,访问一般的非信号资源,提高成功概率的两倍相比,经典的,输出的数量足够大。

英文摘要:

Understanding the role that quantum entanglement plays as a resource in various information processing tasks is one of the crucial goals of quantum information theory. Here we propose a new perspective for studying quantum entanglement: distributed computation of functions without communication between nodes. To formalize this approach, we propose identity games. Surprisingly, despite of no-signaling, we obtain that non-local quantum strategies beat classical ones in terms of winning probability for identity games originating from certain bipartite and multipartite functions. Moreover we show that, for majority of functions, access to general non-signaling resources boosts success probability two times in comparison to classical ones, for number of outputs large enough.
