Coherent spin displacement. a Schematics of the time-dependent sequence applied on gates V 1 and V 2 to perform the electron displacement. N t is the number of loops performed by the electrons and τ r is the duration spent in each charge configuration ((1, 1, 0), (0, 1, 1), (1, 0, 1)). Considering the rise time of the pulse generator, the electrons are adiabatically transferred between the dots (see “Methods” section). b Schematics of the spatial displacement of the electrons during a single rotation. Most of the displacement is occurring while the electrons are trapped in moving quantum dots. c Singlet probability as a function of the time τ s for the case where the electrons are rotating between separated charge configurations with τ r = 1.7 ns (electron displacement with minimized static phase) and B = 200 mT. The data are fitted with an exponential decay with a characteristic time τ Decay equal to 78 ns. Inset: Singlet probability as a function of the time τ s for B = 150 mT and τ r = 2.5 ns. The data are fitted with a two-exponential decay. The solid pink (red) line is a fit of the fast (slow) decay. We notice very similar spin mixing time-evolution with displacement for different tunnel-coupling conditions (see Supplementary Note 6 and Supplementary Fig. 6)
