Query: Collectively enhanced thermalization via multiqubit collisions   We investigate the evolution of a target qubit caused by its multiple random
collisions with $N$-qubit clusters. Depending on the cluster state, the
evolution of the target qubit may correspond to its effective interaction with
a thermal bath, a coherent (laser) drive, or a squeezed bath. In cases where
the target qubit relaxes to a thermal state its dynamics can exhibit a quantum
advantage, whereby the target-qubit temperature can be scaled up proportionally
to $N^2$ and the thermalization time can be shortened by a similar factor,
provided the appropriate coherence in the cluster is prepared by non-thermal
means. We dub these effects quantum super-thermalization due to its analogies
to super-radiance. Experimental realizations of these effects are suggested.
