几乎确定逃离黑洞
Almost Certain Escape from Black Holes
摘要:
本文探讨如何黑洞可能计算在最近的模型的黑洞的最终状态。这些模型表明,量子信息可以通过类似于隐形传态的过程从黑洞中逃逸。它们需要一个特定的最终状态,并限制坍缩物质与入射霍金辐射之间的相互作用,以使量子信息逃逸。本文表明,对于一个任意的最终状态和物质与霍金辐射之间的一般相互作用,量子信息如何形成的洞和洞内的物质进行的任何计算的结果逃脱保真度指数接近1。
英文摘要:
This paper examines how black holes might compute in light of recent models of the black-hole final state. These models suggest that quantum information can escape from the black hole by a process akin to teleportation. They require a specific final state and restrictions on the interaction between the collapsing matter and the incoming Hawking radiation for quantum information to escape. This paper shows that for an arbitrary final state and for generic interactions between matter and Hawking radiation, the quantum information about how the hole was formed and the results of any computation performed by the matter inside the hole escapes with fidelity exponentially close to 1.
