# Quantum Statistical Enhancement of the Collective Performance of Multiple Bosonic Engines

## TL;DR

This paper demonstrates that quantum statistical effects in ensembles of indistinguishable bosonic engines can enhance collective thermodynamic performance, unlike distinguishable systems, due to permutation symmetry.

## Contribution

It introduces a quantum statistical mechanism for collective enhancement in bosonic quantum engines, highlighting the role of permutation symmetry.

## Key findings

- Quantum statistical effects lead to performance enhancement in bosonic engines.
- Permutation symmetry is key to the collective thermodynamic advantage.
- Enhancement is absent in systems with distinguishable resources.

## 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.
