论文摘要
统一的进化使一个cauchy表面上的纯状态在另一个cauchy表面演变为纯状态。外向的鹰辐射仅是考奇表面晚期的子系统。当整体系统纯净时，霍克辐射量纯度需要纯度的纯度要求。即使在\ textit {flat}时期，我们也会看到此要求将导致防火墙，从而无效。当通过量子重力效应解决奇异性时，信息要么存储在黑洞内部模式与外向模式之间的纠缠中，要么存储在几何和鹰辐射之间的相关性中。我们将提出一个简单的论点，即即使在半古典制度中，信息也（至少部分）存储在几何和鹰辐射之间的相关性中。
Unitary evolution makes pure state on one Cauchy surface evolve to pure state on another Cauchy surface. Outgoing Hawking radiation is only subsystem on the late Cauchy surface. The requirement that Hawking radiation to be pure amounts to require purity of subsystem when total system is pure. We will see this requirement will lead to firewall even in \textit{flat} spacetime, and thus is invalid. Information is either stored in the entanglement between field modes inside black hole and the outgoing modes or stored in correlation between geometry and Hawking radiation when singularity is resolved by quantum gravity effects. We will give a simple argument that even in semi-classical regime, information is (at least partly) stored in correlation between geometry and Hawking radiation.
