FIG. 1: Two cases of a three-site system are considered. a) Scaled schematic of system spacing and energy levels with details of variable site energies ( E n ) and intersite F¨ orster coupling strengths ( J mn ). For QDs with transition dipole moments aligned perpendicular to R mn , J mn = 100 meV /R 3 $_{mn}$, with R mn in nanometers [30]. b) Frequency correlation function for a super-ohmic spectral density. Energy basis transition frequencies for case 1 ( 2 ) are indicated by solid (dashed) vertical lines. 5 (a) Case 1 3 E = 0.9 meV E = 0.7 meV 2 E = 0 1 1 2 3 R = 20.7 nm 23 R =  13 9.6 nm J = 0.004 meV 12 J = 0.11 meV 13 J = 0.01 meV 23 Case 2 E = 0 1 E =  2.4 meV 2 3 E = 3.2 meV 1 2 3 R = 13.6 nm 23 R =  13 6.3 nm J = 0.40 meV 13 J = 0.01 meV 12 J = 0.04 meV 23 31 2 21 2 32 1 21 1 31 1 32 2 (b)
