Effect of dephasing on superadiabatic three-level quantum driving
The robustness of the three-level transitionless quantum driving proposed by Giannelli and Arimondo [L. Giannelli and E. Arimondo, Phys.Rev.A89,033419(2014)] is investigated.

| Summary: | The robustness of the three-level transitionless quantum driving proposed by Giannelli and Arimondo [L.
Giannelli and E. Arimondo,
Phys.Rev.A89,033419(2014)] is investigated. In the case when the excited
state is barely populated during the evolution, its decay rate has little effect on the adiabatic population
transfer. However, the dephasing which is due to collisions or phase fluctuations of the driving fields will
produce a significant effect on the evolution. We found that the dephasing reduces the performance of the
population transfer and the fidelity can be far below the quantum computation target even for small dephasing
