A single-shot adiabatic pulse maps qubit detuning to a near-binary response with simulated sensitivity comparable to a 100-shot Bayesian Ramsey estimate.
This results in the tracker being unable to keep pace with fast changes in detuning; this manifests as a low-pass filter whose cut- off scales with the gain

Approaching the Fundamental Limit of Single-Shot Qubit Frequency Tracking with an Adiabatic Tangentially-Modulated Pulse
A single-shot adiabatic pulse maps qubit detuning to a near-binary response with simulated sensitivity comparable to a 100-shot Bayesian Ramsey estimate.
