From: Disorder-assisted quantum transport in suboptimal decoherence regimes
Transport efficiency η on the hypercube of dimension 4 as a function of the disorder parameter δϵ and the logarithm of the dephasing rate γϕ, starting with a statistical mixture of all vertices with κ = 1 and for different values of the recombination rate: Γ = 10−2, 10−3, 10−4, plotted respectively in (a–c).
The efficiency at each point is obtained by averaging over 100 random configurations of site energies disorder. The qualitative behaviour of the transport efficiency is very similar to the binary tree (see Fig. 3). All units are given in terms of the nearest neighbour coupling V.
