从黑洞辐射中提取初态信息

Extracting information about the initial state from the black hole radiation

Kinjalk Lochan, T. Padmanabhan

摘要:

黑洞信息悖论的关键在于,坍缩时空中量子场初始状态的完整信息对于未来的渐近观测者来说是不可用的,这与酉量子理论的预期不符。我们研究了初始量子态的印记包含在一个特定的类扭曲的黑洞辐射和识别类的状态,可以部分/完全重建的信息包含在其中。即使是一般的内部状态,我们也可以发现一些具体的信息。这些结果表明,\textit{classical}坍缩方案忽略了由此产生的光谱中的丰富信息,对整个坍缩过程进行一致的量子处理可能使我们能够从最终辐射的光谱中检索更多的信息。

英文摘要:

The crux of the black hole information paradox is related to the fact that the complete information about the initial state of a quantum field in a collapsing spacetime is not available to future asymptotic observers, belying the expectations from a unitary quantum theory. We study the imprints of the initial quantum state contained in a specific class of distortions of the black hole radiation and identify the classes of in-states which can be partially/fully reconstructed from the information contained within. Even for the general in-state, we can uncover some specific information. These results suggest that a \textit{classical} collapse scenario ignores this richness of information in the resulting spectrum and a consistent quantum treatment of the entire collapse process might allow us to retrieve much more information from the spectrum of the final radiation.
