Fig. 5: ST0-oscillations and pulse for coherent shuttling.
From: Spin-EPR-pair separation by conveyor-mode single electron shuttling in Si/SiGe
a Charge stability-diagram of the DQD in Fig. 4a. b ST0-oscillation as a function waiting for time τDQD at stage S. The singlet probability PS is measured by applying the pulse from panel c spending various time τDQD at stage S. The solid line is fit to the data. inset: Readout histogram with threshold (dashed line) determined by the fitted crossing point of the two Gaussians. c Schematic representation of the experiment pulse. Numbers correspond to stages in a and Fig. 4a. d Schematic of the additional stages complementing the pulse scheme in c for doing the spin-shuttling measurement. They slot in panel c in between the separation and the PSB-freeze-RO pulse segments. The SRL section represents any applied shuttle pulse.
