Abstract
We consider an ensemble of indistinguishable quantum machines and show that quantum statistical effects
can give rise to a genuine quantum enhancement of the collective thermodynamic performance. When multiple
indistinguishable bosonic work resources are coupled to an external system, the internal energy change of the
external system exhibits an enhancement arising from permutation symmetry in the ensemble, which is absent
when the latter consists of distinguishable work resources.
