# Efficient and coherent excitation transfer across disordered molecular networks

## TL;DR

This paper demonstrates that disordered molecular networks can facilitate highly efficient, coherent excitation transfer that remains robust against environmental noise, potentially explaining energy transfer in photosynthesis.

## Contribution

It reveals that finite disordered molecular networks can achieve efficient, coherent excitation transfer with robustness to dephasing, linking to biological energy transfer mechanisms.

## Key findings

- Efficient excitation transfer occurs in disordered networks.
- Transfer is robust against ambient dephasing.
- Strong multi-site entanglement is associated with transfer.

## Abstract

We show that finite-size, disordered molecular networks can mediate highly efficient, coherent excitation transfer which is robust against ambient dephasing and associated with strong multi-site entanglement. Such optimal, random molecular conformations may explain efficient energy transfer in the photosynthetic FMO complex.
