论文摘要
在JT重力的背景下,我们考虑了将能量和熵携带到黑洞中的物体的信息回收问题,在这种情况下,反应问题可以准确地解决。我们验证了海顿 - 普雷斯基尔场景的主要方面,但进行了一些改进。我们表明,该信息以冗余方式在鹰辐射中编码,这是纠正量子误差代码所预期的。我们展示了与信息恢复相关的量子极端表面如何具有python的午餐的形式,从而表明解码的复杂性是在黑洞的熵偏移和物体熵的组合中指数的。我们还表明,一个插入的观察者必须在地平线上具有平稳的体验,并且我们在黑洞辐射之前计算出它们在黑洞内的适当时间。
We consider the issue of information recovery for an object carrying energy and entropy into a black hole using the generalized entropy formalism, in the context of JT gravity where the backreaction problem can be solved exactly. We verify the main aspects of the Hayden-Preskill scenario but with some refinements. We show that the information is encoded in the Hawking radiation in a redundant way, as expected for a quantum error correcting code. We show how quantum extremal surfaces associated to information recovery have the form of a python's lunch and thereby show that the complexity of decoding is exponential in a combination of the entropy shift of the black hole and the entropy of the object. We also show that an infalling observer must have a smooth experience at the horizon and we calculate their endurance proper time inside the black hole before they are radiated out.
