Population transfer under local dephasing

Abstract Stimulated Raman adiabatic passage is a well-known technique for quantum population transfer due to its robustness again various sources of noises. Here we consider from one spin another via an intermediate which under dephasing noise. We obtain analytic expression the efficiency specific driving protocol, showing that could reduce efficiency, but effect also be suppressed with stronger laser coupling or longer duration. commonly used shows this picture still qualitatively correct.
