    "abstract": "We propose a scheme to eliminate the effect of non-nearest-neighbor qubits in\npreparing cluster state with double-dot molecules. As the interaction\nHamiltonians between qubits are Ising-model and mutually commute, we can get\npositive and negative effective interactions between qubits to cancel the\neffect of non-nearest-neighbor qubits by properly changing the electron charge\nstates of each quantum dot molecule. The total time for the present multi-step\ncluster state preparation scheme is only doubled for one-dimensional qubit\nchain and tripled for two-dimensional qubit array comparing with the time of\nprevious protocol leaving out the non-nearest-neighbor interactions.",
