High-fidelity Stimulated Raman adiabatic passage — •Julian Dimitrov and Nikolay Vitanov — Center for Quantum Technologies, Faculty of Physics, Sofia University, James Bourchier 5 blvd., 1164 Sofia, Bulgaria

We present a comparative study of various approaches toward high-fidelity Stimulated Raman adiabatic passage (STIRAP). This technique for population transfer in a three-state quantum system is widely used because of its robustness to errors in the driving fields and the fact that the intermediate state is unpopulated in the adiabatic limit. Its main drawbacks are the large pulse areas needed to achieve adiabaticity and the necessity for a two-photon resonance between the two end states, which make it difficult to achieve very high population transfer efficiency. Here we compare two main approaches to high-efficiency STIRAP: by using pulse shaping of the driving fields and by using composite sequences. We assume that only two fields are present and discard the often used third field, which introduces unnecessary redundancy.
