论文摘要
时期的动力学放松了信息，这是在随着时间前进的演变过程中引起的，并以复杂的哈密顿式化。我们表明，如果此外，拼凑而成的信息部分受到本地测量的部分损害，那么仍然可以通过应用时间转换协议来处理这种损坏。此信息恢复是由特定局部变量的某个超时订购的相关器的长期饱和值描述的。我们还提出了一项简单的测试，该测试区分量子和可逆的经典混沌信息。
A time-reversed dynamics unwinds information scrambling, which is induced during the time-forward evolution with a complex Hamiltonian. We show that if the scrambled information is, in addition, partially damaged by a local measurement, then such a damage can still be treated by application of the time-reversed protocol. This information recovery is described by the long-time saturation value of a certain out-of-time-ordered correlator of local variables. We also propose a simple test that distinguishes between quantum and reversible classical chaotic information scrambling.
