  We propose an architecture based on Quantum cellular Automata which allows
the use of only one type of quantum gates per computational step in order to
perform nearest neighbor interactions. The model is built in partial steps,
each one of them analyzed using nearest neighbor interactions, starting with
single qubit operations and continuing with two qubit ones. The effectiveness
of the model is tested and valuated by developing a quantum circuit
implementing the Quantum Fourier Transform. The important outcome of this
validation was that the operations are performed in a local and controlled
manner thus reducing the error rate of each computational step.
