# Recovery of Damaged Information and the Out-of-Time-Ordered Correlators.

@article{Yan2020RecoveryOD, title={Recovery of Damaged Information and the Out-of-Time-Ordered Correlators.}, author={Bin Yan and Nikolai A. Sinitsyn}, journal={Physical review letters}, year={2020}, volume={125 4}, pages={ 040605 } }

The evolution with a complex Hamiltonian generally leads to information scrambling. A time-reversed dynamics unwinds this scrambling and thus leads to the original information recovery. 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…
