Derivative removal by adiabatic gate
WebIn mathematics, a derivation is a function on an algebra which generalizes certain features of the derivative operator. Specifically, given an algebra A over a ring or a field K, a K … WebFor superconducting circuits, perhaps the best known is the DRAG technique (Derivative Removal by Adiabatic Gate) [3,4], which was designed to minimize leakage er- rors for single qubit gates in a weakly anharmonic qubit. DRAG has also been employed to improve the delity of a Rydberg-blockade two-qubit entangling gate [5].
