Counterdiabatic driving for random-gap Landau-Zener transitions
Georgios Theologou, Mikkel F. Andersen, Sandro Wimberger
The Landau--Zener (LZ) model describes a two-level quantum system that undergoes an avoided crossing. In the adiabatic limit, the transition probability vanishes. An auxiliary cont…

Comparison of Two Optimization Methods for a Rydberg Quantum Gate
Luis S. Yagüe Bosch, Sandro Wimberger
A shortcut-to-adiabaticity is compared with a numerically optimized protocol for implementing a high-fidelity quantum gate on Rydberg atoms. The counterdiabatic method offers an an…

Reversing adiabatic state preparation in few-level quantum systems
L. Romanato, N. Eshaqi-Sani, L. Lepori +3
We present a detailed study of an adiabatic state preparation in an effective three-level quantum system. States can be prepared with high speed and fidelity by adding a counterdia…
