DRAG (Derivative Removal by Adiabatic Gate) pulses shape the control waveform to cancel leakage to higher energy levels (|f⟩, |g2⟩, etc.). The optimal coefficient minimizes this leakage while maintaining gate speed. This calibration is crucial for high-fidelity two-qubit gates and complex quantum algorithms where leakage accumulates.
