WebJun 24, 2016 · (a) Schematic for the echoed cross-resonance gate with active cancellation on the target qubit. 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. 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]. cz scorpion evo 3 wallpaper

Webreview the Derivative Removal by Adiabatic Gate (DRAG) framework. DRAG is multi-transition variant of counterdiabatic driving, where multiple low-lying gapped states in an adiabatic evolution can be avoided simultaneously, greatly reducing operation times … 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 … cz scorpion evo 3 s2 micro for sale gunbroker
