Observing the magic Mpemba effect in localized dynamics on a digital quantum computer
Researchers report using a digital quantum computer to search for a magic-ordering reversal analogous to the Mpemba effect in localized dynamics. They investigate whether a state with lower initial nonstabilizerness can overtake one with higher initial nonstabilizerness as both approach their asymptotic magic values. The work appears as an arXiv preprint.

This could make magic generation a tunable feature in near-term digital quantum simulations by selecting initial states for their magic growth rate rather than their starting magic.
If the observed reversal is reproducible and controllable, it implies that a lower-magic starting point can outpace a higher-magic one, which would let algorithm designers reduce the effective circuit depth or gate overhead needed to reach a target nonstabilizerness in variational or simulation workloads.
