Researchers used a circuit-based protocol with quantum processors to demonstrate how postselection allows for interpreting an experiment as a simulation of a consistent time loop and reliable information recovery. The success probability of this protocol is governed by out-of-time-ordered correlations, a standard measure of quantum information scrambling.
