The cluster state quantum computation is a versatile approach to build a scalable quantum computer. In this thesis we theoretically demonstrate that a one dimensional array of double quantum dots with long spin relaxation time can evolve to a cluster state via capacitive coupling to a transmission line resonator. By applying an oscillating voltage to gates of the double quantum dots, we prove that the evolution operator for such interaction is an Ising-like operator. Subsequently, the interacting qubits will become highly entangled that we realize a cluster state. Furthermore, we propose an experiment to investigate validity of our theoretical method. Considering the current advanced technology in semiconductor nanofabrication, our proposed structure can be integrated on a chip where provides scalability and convenient control of the qubits. The scalability of our scheme implies that we can expand this structure to higher dimensional arrays of the qubits where paves the way for further experimental investigation on the theory of measurement-based quantum computation.
