Spin-orbit induced spin-qubit control in nanowires
arXiv:cond-mat/0612293 · doi:10.1088/1742-6596/61/1/061
Abstract
We elaborate on a number of issues concerning our recent proposal for spin-qubit manipulation in nanowires using the spin-orbit coupling. We discuss the experimental status and describe in further detail the scheme for single-qubit rotations. We present a derivation of the effective two-qubit coupling which can be extended to higher orders in the Coulomb interaction. The analytic expression for the coupling strength is shown to agree with numerics.
