摘要
Abstract
A scheme to create coherent superposition states in double Λ-type six-level system is proposed. This system is based upon a Λ-type system with the application of a control field and a fractional stimulated Raman adiabatic passage (f-STIRAP). An arbitrary superposition state can be generated in the adiabatic limit and in the diabatic system. Without the diabatic system, the preselected coherent superposition state is not created. We give a numerical simulation of coherence generation in the six-level system and demonstrate our analysis is true. It is shown that an arbitrary atomic superposition states can be created by varying the delay of the control pulse.关键词
