# Optimally designed quantum transport across disordered networks.

@article{Walschaers2012OptimallyDQ, title={Optimally designed quantum transport across disordered networks.}, author={Mattia Walschaers and Jorge Fernandez-de-Cossio-Diaz and Roberto Mulet and Andreas Buchleitner}, journal={Physical review letters}, year={2012}, volume={111 18}, pages={ 180601 } }

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