# Energy transport in the presence of entanglement

## TL;DR

This paper studies how initial entanglement influences energy transport in a network, revealing short-term enhancement and long-term damping effects, with implications for quantum technology applications.

## Contribution

It provides a detailed analysis of the interplay between entanglement, dephasing, and energy transport efficiency over different timescales.

## Key findings

- Initial entanglement boosts short-term energy transport efficiency.
- Dephasing reduces quantum correlations over time.
- Noise-assisted transport dominates at longer times.

## Abstract

In this work, we investigate how the presence of initial entanglement affects energy transport in a network. The network have sites dedicated to incoherent input or output of energy and intermediate control sites where initial entanglement can be established. For short times, we found that initial entanglement in the control sites provides a robust efficiency enhancer for energy transport. For longer times, dephasing considerably damps the quantum correlations, and the advantage of having initial entanglement tends to disappear in favor of the well known mechanism of noise-assisted transport. We careful study these two mechanisms in this work, and we believe our findings may be usuful for a better understanding of the relation between nonclassicality and transport, a topic of potential interest for quantum technologies.
