黑洞信息悖论是一个人们知之甚少的问题。人们通常认为霍金的论点没有被精确表述，对自然发生的量子修正进行更仔细的计算将使辐射过程变得统一。通过证明对前导霍金计算的小修正不能消除辐射和空穴之间的纠缠，我们证明情况并非如此。我们将霍金的论点表述为一个“定理”：假设“传统”物理学处于地平线，并且通常假设局域性，我们将被迫进入混合状态或残余状态。我们还认为，不能通过援引 AdS/CFT 二元性来解释这一问题。我们总结了黑洞量子物理学的最新结果，这些结果表明黑洞的内部具有“绒球”结构。这种重要的微观状态结构解决了信息悖论，并给出了经典直觉如何在黑洞物理学中崩溃的定性图景。
The black hole information paradox is a very poorly understood problem. It is often believed that Hawking's argument is not precisely formulated, and a more careful accounting of naturally occurring quantum corrections will allow the radiation process to become unitary. We show that such is not the case, by proving that small corrections to the leading order Hawking computation cannot remove the entanglement between the radiation and the hole. We formulate Hawking's argument as a 'theorem': assuming 'traditional' physics at the horizon and usual assumptions of locality we will be forced into mixed states or remnants. We also argue that one cannot explain away the problem by invoking AdS/CFT duality. We conclude with recent results on the quantum physics of black holes which show that the interior of black holes have a 'fuzzball' structure. This nontrivial structure of microstates resolves the information paradox and gives a qualitative picture of how classical intuition can break down in black hole physics.
