论文摘要
在本说明中，我们讨论了量子传送方案的拓扑实现。这种实现有助于跟踪系统中量子相关的演变。然后建议，类似协议的实施可以用作有因果关系之间的信息传递过程的玩具模型，例如应该在量子黑洞的单一演变中进行的一个信息转移。 Hawking Quanta为传送道提供了必要的纠缠对，并提供了产生鹰对的相同的相互作用机制，在进化的后期摧毁了纠缠。传送协议的不同步骤的特征是与断开区域相关的熵，并且可以为霍金辐射的熵引入页面曲线的类似物。 ``黑洞''内部的某些区域似乎实际上编码了外部的信息，因此自然而然地用半经典重力分析的``岛''识别它们是很自然的。
In this note we discuss a topological realization of the quantum teleportation protocol. Such a realization facilitates keeping track of the evolution of quantum correlations in the system. It is then suggested, that an implementation of a similar protocol can serve as a toy model of a process of information transfer between causally disconnected regions, such as the one that should take place in a unitary evolution of a quantum black hole. Hawking quanta provide the necessary entangled pairs for the teleportation channel, and the same interaction mechanism that creates the Hawking pairs, destroys the entanglement at the late stages of the evolution. Different steps of the teleportation protocol are characterized by the entropies associated with the disconnected regions, and one can introduce an analog of the Page curve for the entropy of the Hawking radiation. Some regions of the ``black hole'' interior appear to actually encode the information of the exterior, so it is natural to identify them with the ``islands'' of the semiclassical gravity analysis.
