Phase-Noise Requirements for Integrated Solid-State Spin-Qubit Control Electronics
A design procedure that turns a spin qubit's coherence properties into quantitative noise specifications for its microwave control electronics. Local-oscillator phase noise and timing jitter are treated as additional dephasing sources alongside the qubit's environmental noise, and the filter-transfer function formalism yields the coherence loss for a given control sequence. This lets a designer set the tolerable phase-noise budget of a compact, integrated signal source from the qubit's coherence time, intrinsic noise spectrum, and required fidelity.
