A spin-triplet encoding based on valley-singlet states makes shuttling fidelities in Si/SiGe quantum wells higher and more robust to small valley splittings by suppressing Landau-Zener excitations.
A Tukey-window-based smooth velocity shuttling protocol reduces valley excitations and average spin infidelity in disordered Si/SiGe quantum dots via analytical design and statistical simulations.
Theoretical expressions for singlet return probability in multivalley Si double quantum dots near spin-valley resonances are derived, accounting for valley occupations, and validated against experiments to map valley splittings and probe g-factor dependence.
