Can quantum-information theory shed light on black-hole evaporation? By entangling the in-fallen matter with an external system we show that the black-hole information paradox becomes more severe, even for cosmologically sized black holes. We rule out the possibility that the information about the in-fallen matter might hide in correlations between the Hawking radiation and the internal states of the black hole. As a consequence, either unitarity or Hawking's semiclassical predictions must break down. Any resolution of the black-hole information crisis must elucidate one of these possibilities.
量子信息理论能阐明黑洞蒸发问题吗？通过将落入黑洞的物质与外部系统纠缠在一起，我们发现，即使对于宇宙尺度的黑洞，黑洞信息悖论也变得更加严重。我们排除了关于落入黑洞物质的信息可能隐藏在霍金辐射与黑洞内部状态之间相关性中的可能性。因此，幺正性或霍金的半经典预测必有其一失效。任何解决黑洞信息危机的方案都必须阐明这些可能性中的一种。
