Preparation of nondegenerate coherent superpositions in a three-state ladder system assisted by Stark shifts
Preparation of nondegenerate coherent superpositions in a three-state ladder system assisted by Stark shifts
We propose a technique to prepare coherent superpositions of two nondegenerate quantum states in a three-state ladder system, driven by two simultaneous fields near resonance with an intermediate state. The technique, of potential application to enhancement of nonlinear processes, uses adiabatic passage assisted by dynamic Stark shifts induced by a …
