We have theoretically studied the excitation transfer between distant quantum dots in a photonic crystal waveguide. Due to Anderson localization of disordered position and size of the photonic crystal holes was found to have a highly nontrivial effect on the interaction. We have simulated realistic systems with different magnitudes of the disorder and showed that while localization indeed has a profound effect on both range and magnitude of the dot-dot excitation transfer rate at several μm distance. The average excitation transfer rate was found to be larger than 10eV at distance on the order of 10m . The transfer time to this corresponded was on the order of 10 ps, close to the single qubit operation time and much shorter than the decoherence time measured. The obtained results were found in good agreement with previous results.
