WebApr 19, 2024 · One very promising method that recently emerged is the two-quadrature derivative-removal-by-adiabatic-gate (DRAG) technique [ 39, 40, 41 ]. DRAG allows high-fidelity qubit rotations with significant gate speedups. The main idea is that a second control pulse that is the time derivative of the first creates a spectral hole. http://export.arxiv.org/pdf/1509.05470v2
