Abstract
This paper demonstrates electrically driven single spin Rabi oscillations in the ``flopping mode'' regime, where the wavefunction of a single electron is delocalized across the two sites of a silicon double quantum dot. Comparable Rabi frequencies are achieved using 250 times less drive power in the flopping mode, as compared with electric dipole spin resonance in a single quantum dot. The flopping-mode driving regime will enable low power control of large-scale spin qubit arrays.
