The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Numerical simulations demonstrate that the proposed CMCCD achieves higher gate fidelity than conventional CCD schemes. We further implement and compare different CCD protocols using an electron spin-qubit in an isotopically purified 28Si-MOS quantum dot and evaluate its robustness by applying static detuning and Rabi frequency errors. The robustness is significantly improved compared to standard Rabi-drive.

C2weakest assumption

The assumption that the simultaneous amplitude and phase modulation can be realized with sufficient precision and without introducing additional high-frequency noise or calibration errors that would offset the theoretical cancellation of the counter-rotating term.

C3one line summary

CM-CCD cancels the counter-rotating term via dual amplitude-phase modulation, yielding higher gate fidelity and improved robustness to static errors in a 28Si-MOS quantum-dot spin qubit.
