Abstract We propose a new structure for quantum computing via spin qubits with high fidelity. Each spin qubit corresponds to two electrons in a nanowire double quantum dot, with the singlet and one of the triplets as the logical qubit states. The entangling gate is effected by virtual charge dipole transitions. We include noise to show the feasibility of this scheme under current experimental conditions.
