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

Abstract

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.
