在海登-普雷斯基尔思想实验中，霍金辐射在量子态被扔进黑洞之前被发射出来，沿着后来收集到的辐射被用来解码量子态。一个自然的问题是，如果所存储的早期辐射被损坏或受到退相干，和/或解码协议被不完美地执行，可恢复性如何受到影响。我们研究了在早期辐射存储中存在退相干或噪声的思想实验中的可恢复性。
In the Hayden-Preskill thought experiment, the Hawking radiation emitted before a quantum state is thrown into the black hole is used along with the radiation collected later for the purpose of decoding the quantum state. A natural question is how the recoverability is affected if the stored early radiation is damaged or subject to decoherence, and/or the decoding protocol is imperfectly performed. We study the recoverability in the thought experiment in the presence of decoherence or noise in the storage of early radiation.
