扩展的非局部对策

Extended Nonlocal Games

Vincent Russo

摘要:

纠缠和非定域性的概念是量子信息理论中最引人注目的组成部分。更好地理解这些概念的一个工具是非局部博弈模型;一个抽象物理系统模型的数学框架。最简单的非局部博弈的例子包括两个参与者,爱丽丝和鲍勃,一旦博弈开始,他们就不允许彼此通信,他们合作对抗一个被称为裁判的对手。本论文的重点是一类称为扩展非局部博弈的博弈,非局部博弈是其中的一个子集。在扩展的非局部博弈中,参与者最初与裁判共享三方状态。在这样的游戏中,除了Alice和Bob对裁判发送的问题的回答之外,Alice和Bob的获胜条件可以取决于裁判在其共享量子态的部分上进行的测量的结果。我们建立了扩展的非局部博弈的框架,并研究了它们的性质以及它们与非局部博弈的关系。

英文摘要:

The notions of entanglement and nonlocality are among the most striking ingredients found in quantum information theory. One tool to better understand these notions is the model of nonlocal games; a mathematical framework that abstractly models a physical system. The simplest instance of a nonlocal game involves two players, Alice and Bob, who are not allowed to communicate with each other once the game has started and who play cooperatively against an adversary referred to as the referee. The focus of this thesis is a class of games called extended nonlocal games, of which nonlocal games are a subset. In an extended nonlocal game, the players initially share a tripartite state with the referee. In such games, the winning conditions for Alice and Bob may depend on outcomes of measurements made by the referee, on its part of the shared quantum state, in addition to Alice and Bob's answers to the questions sent by the referee. We build up the framework for extended nonlocal games and study their properties and how they relate to nonlocal games.
