Robust population transfer by finite chirping method in a two-level system

Considering a two-level quantum system, we have proposed and represented a new approach for robust population transfer. In this scheme, the laser frequency has been swept in a finite time interval which simplifies the experimental limitations of the population transfer process. It is shown that using the Jaynes-Cummings model and engineering the coupling strength, the frequency sweeping range and its time interval, it is possible to achieve a robust, stable and full population transfer.
