Quantum driving protocols for a two-level system: From generalized Landau-Zener sweeps to transitionless control

Quantum driving protocols for a two-level system: From generalized Landau-Zener sweeps to transitionless control

We present experimental results on the preparation of a desired quantum state in a two-level system with the maximum possible fidelity using driving protocols ranging from generalizations of the linear Landau-Zener protocol to transitionless driving protocols that ensure perfect following of the instantaneous adiabatic ground state. We also study the …
