Counteracting systems of diabaticities using DRAG controls: The status after 10 years
L. S. Theis, F. Motzoi, S. Machnes +1
The task of controlling a quantum system under time and bandwidth limitations is made difficult by unwanted excitations of spectrally neighboring energy levels. In this article we…
Restless Tuneup of High-Fidelity Qubit Gates
M. A. Rol, C. C. Bultink, T. E. O'Brien +11
We present a tuneup protocol for qubit gates with tenfold speedup over traditional methods reliant on qubit initialization by energy relaxation. This speedup is achieved by constru…
Nonadiabatic corrections to fast dispersive multiqubit gates involving Z control
L. S. Theis, F. K. Wilhelm
We review a time-dependent version of the Schrieffer-Wolff transformation that accounts for real-time control of system parameters, soon to be rendered possible on a broad basis du…
High-fidelity Rydberg-blockade entangling gate using shaped, analytic pulses
L. S. Theis, F. Motzoi, F. K. Wilhelm +1
We show that the use of shaped pulses improves the fidelity of a Rydberg blockade two-qubit entangling gate by several orders of magnitude compared to previous protocols based on s…
Simultaneous gates in frequency-crowded multilevel systems using fast, robust, analytic control shapes
L. S. Theis, F. Motzoi, F. K. Wilhelm
We present a few-parameter ansatz for pulses to implement a broad set of simultaneous single-qubit rotations in frequency-crowded multilevel systems. Specifically, we consider a sy…
Engineering adiabaticity at an avoided crossing with optimal control
T. Chasseur, L. S. Theis, Y. R. Sanders +2
We investigate ways to optimize adiabaticity and diabaticity in the Landau-Zener model with non-uniform sweeps. We show how diabaticity can be engineered with a pulse consisting of…
