Derivative reduction by adiabatic gate
WebFeb 5, 2024 · A related method based on derivative removal by adiabatic gate has been used to eliminate leakage of the drives in weakly anharmonic systems. We further employ our saSTIRAP protocol based on two-photon counterdiabatic driving to demonstrate a … WebMar 21, 2024 · In this work, we used the Derivative Reduction by Adiabatic Gate (DRAG) technique, proposed in Ref. , and largely employed in literature for the reduction of SPAM errors [75,76,78,86,87,88,89]. The DRAG technique corrects the pulse shape Ω ( t ) by introducing a term depending on the derivative of the control pulse d Ω ( t ) / d t [ 74 ],
