We introduce a scheme for realizing universal quantum computing in a linear nearest neighbor architecturewith fixed couplings. We first show how to realize a controlled-NOT gate operation between two adjacentqubits without having to isolate the two qubits from qubits adjacent to them. The gate operation isimplemented by applying two consecutive pulses of equal duration, but varying amplitudes, on the targetqubit. Since only a single control parameter is required in implementing our scheme, it is very efficient.We next show how our scheme can be used to realize single qubit rotations and two-qubit controlledunitaryoperations. As most proposals for solid state implementations of a quantum computer use a onedimensionalline of qubits, the schemes presented here will be extremely useful.
