Optimization of doping, bias, and geometry in SiC p-i-n diodes reduces charge noise and optical linewidth for embedded divacancy spin centers, with a new leakage-current noise formalism mitigated by defect placement away from surfaces.
A system-level design methodology for scalable fluxonium processors with double-transmon couplers that supports high-fidelity gates, fast reset, and dispersive readout through frequency partitioning under realistic constraints.
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.
