Transport phenomena are ubiquitous throughout different fields of research. Some of the most common examples of transport analysis are seen in the fields of physics, chemistry and biology1. In recent years, energy transport assisted by noise2,3,4 has attracted a great deal of attention, partly because of its potential role in the development of future artificial light-harvesting technologies5,6,7. This intriguing phenomenon has theoretically been shown to occur in several quantum8,9,10,11,12,13,14 and classical15,16,17,18 systems; however, efforts towards its experimental observation had not been presented until very recently. Viciani et al.19 showed an enhancement in the energy transport of optical fiber cavity networks, where the effect of noise on the system was introduced by averaging the optical response of several network configurations with different cavity-frequency values. In a closely related experiment, Biggerstaff et al.20 demonstrated an increase in the transport efficiency of a laser-written waveguide network, where decoherence effects were simulated by averaging the output signal of the waveguide array considering different illumination wavelengths. Using the same photonic platform, Caruso et al.21 observed an enhanced transport efficiency when suppressing interference effects in the transport dynamics of a photonic network. In this experiment, noise was implemented by dynamically modulating the propagation constants of the waveguides, which is the natural way for producing decohering noise, as it has been experimentally demonstrated in the context of quantum random walks22,23,24.
