论文摘要
这项工作说明了量子游戏理论可能应用于量子信息区域，尤其是量子密码学的领域。该研究提出了基于Flitney和Abbott设计的Monty Hall游戏的量子版本的两个量子密钥分布（QKD）协议。与大多数QKD协议不同，将要提取的密钥提取的位编码为基础选择（如BB84中），这些位是在操作选择中编码的。第一个提出的协议使用QUTRIT来描述弗利特尼和雅培提出的同一游戏运营商。第二个建议背后的动机是通过调整QUTRIT协议的形式主义来简化可能的物理实现，以使用Qubits和简单的逻辑量子门。在这两个协议中，安全性都依赖于违反铃铛型不平等，在每种情况下为六个Qutrits而言。结果显示出比E91方案更高的违规比率。
This work illustrates a possible application of quantum game theory to the area of quantum information, in particular to quantum cryptography. The study proposed two quantum key-distribution (QKD) protocols based on the quantum version of the Monty Hall game devised by Flitney and Abbott. Unlike most QKD protocols, in which the bits from which the key is going to be extracted are encoded in a basis choice (as in BB84), these are encoded in an operation choice. The first proposed protocol uses qutrits to describe the state of the system and the same game operators proposed by Flitney and Abbott. The motivation behind the second proposal is to simplify a possible physical implementation by adapting the formalism of the qutrit protocol to use qubits and simple logical quantum gates. In both protocols, the security relies on the violation of a Bell-type inequality, for two qutrits and for six qubits in each case. Results show a higher ratio of violation than the E91 protocol.
