Optimally designed quantum transport across disordered networks

TL;DR

This paper presents a universal mechanism for achieving highly efficient quantum transport in disordered 3D networks by leveraging disorder, centro-symmetry, and spectral properties, with potential biological applications.

Contribution

It introduces a novel design principle for quantum transport that combines disorder and symmetry, controllable through coarse-grained parameters, applicable to biological systems.

Findings

Efficient quantum transport can be achieved in disordered networks using the proposed mechanism.

The mechanism involves interplay of disorder, centro-symmetry, and spectral structure.

Potential biological systems like photosynthetic complexes may utilize this principle.

Abstract

We establish a general mechanism for highly efficient quantum transport through finite, disordered 3D networks. It relies on the interplay of disorder with centro-symmetry and a dominant doublet spectral structure, and can be controlled by proper tuning of only coarse-grained quantities. Photosynthetic light harvesting complexes are discussed as potential biological incarnations of this design principle.
