Abstract

Recent breakthrough demonstrations of the measurement and control of a single atom's electrons and nuclear spins in silicon have added momentum to the pursuit of quantum computing. New results show that two-qubit quantum logic gates can perform with high fidelity, without the need for placing atoms with subnanometer precision.
