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]. WebMar 23, 2024 · length of a geometric gate is 90 ns, and the magnitude of the microwave is tuned to control the rotation angle. The envelope of each pulse is cosine-shaped and the derivative removal by adiabatic gate (DRAG) correction is also used to suppress the leakage to the undesired energy levels, especially j2istate [64].

The πpulse on the control is a 20-ns derivative removal via adiabatic gate (DRAG) pulse, and is buffered by two 10-ns delays. The CR pulses are flat-topped Gaussian pulses, with 3σrise time where σ=5ns. incorporate tt

WebMay 8, 2024 · lows the solution of not just one STA but can remove a system of diabatic errors to a manifold of unwanted low-lying gap states. In this sense, it is a powerful exten-sion of STA methodology. III) While STA usually deals with problems of adiabatic passage techniques, DRAG is equally well applicable to resonant driving problems, also WebThe Derivative Removal by Adiabatic Gate (DRAG) pulse is a standard Gaussian pulse with an additional Gaussian derivative component. It is designed to reduce the frequency spectrum of a normal gaussian pulse near the 1 - 2 transition, reducing the chance of leakage to the 2 state.
