论文摘要
我们研究了静态BTZ黑洞时空中两个Unruh-Dewitt检测器之间的相互信息的相关收集方案。在这里，探测器适当分离的通信和变化带来的效果被设置为可以忽略不计，因此只有黑洞会影响提取的相互信息。我们发现，与纠缠收获方案不同，仅当检测器到达事件范围时，收获的互信息才为零，尽管鹰效应和重力红移既影响互信息的提取，又影响了极端的鹰辐射，抑制探测器的收获。
We investigate the correlation harvesting protocol for mutual information between two Unruh-DeWitt detectors in a static BTZ black hole spacetime. Here, the effects coming from communication and change in proper separation of the detectors are set to be negligible so that only a black hole affects the extracted mutual information. We find that, unlike the entanglement harvesting scenario, harvested mutual information is zero only when a detector reaches an event horizon, and that although the Hawking effect and gravitational redshift both affect the extraction of mutual information, it is extreme Hawking radiation that inhibits the detectors from harvesting.
