论文摘要
最近发现，即使在被入侵者损坏后，也可以通过时间转化的进化来部分恢复加扰的信息。我们重新考虑了信息恢复的起源，并认为经典混乱的存在并不排除它，而仅导致恢复比的定量降低。我们还通过证明了在入侵者行动的纠缠能力方面证明上限对恢复比的上限，从而表明了腐蚀（即与入侵者的纠缠）如何限制恢复。
Recently it was found that scrambled information can be partially recovered by a time-reversed evolution, even after being damaged by an intruder. We reconsider the origin of the information recovery, and argue that the presence of classical chaos does not preclude it and only leads to a quantitative reduction of the recovery ratio. We also show how decoherence (i.e. entanglement with the intruder) limits the recovery, by proving an upper bound on the recovery ratio in terms of the entangling power of the intruder's action.
