EDSR spectroscopy of the spin resonance frequency when shuttling a single spin in (two-tone, see below) conveyor mode. The spins in quantum dots 1 and 2 are initialized in a parallel state. The single spin from dot 2 is displaced by the conveyor potential by a distance controlled by the conveyor time, subjected to a microwave burst, displaced back to dot 2 and read out. The colour scale shows the parallel spin probability as a function of the applied frequency and conveyor time (the expected conveyor displacement is shown on the right axis relative to the plunger gate positions). The inset depicts the travelling-wave potential that smoothly transfers the electron.
