چکیده

Abstract
Efficient and coherent transfer of population between different quantum states. In this study, we delve into the investigation of population transfer in two coupled Λ-type three-level systems using the STIRAP technique. Our research focuses on understanding the dynamics and control of population transfer within these systems. The system Hamiltonian is constructed based on the physical condition of the coupled structure, then the respective time-dependent Schrodinger equation is solved numerically. By analyzing the adiabatic conditions, we explore the interaction between the two coupled Λ-type systems examine the role of various parameters, such as the time of the peak amplitude, and determine the pulse width. Furthermore, we observe the impact of interaction on the transition probability, comparing coupled systems to uncoupled systems. The findings of this study shed light on the underlying mechanisms of STIRAP and contribute to the development of advanced quantum control techniques.
