TL;DR: In this article , the authors considered coherent population transfer in multilevel quantum systems driven by time-delayed pulse trains and showed how to choose the parameters of the trains so that the population dynamics tracks the behavior of a Λ-type three-level system under stimulated Raman adiabatic passage (STIRAP).
Abstract: We consider coherent population transfer in multilevel quantum systems driven by time-delayed pulse trains. We show how to choose the parameters of the trains so that the population dynamics tracks the behavior of a Λ-type three-level system under stimulated Raman adiabatic passage (STIRAP). Efficient population transfer can be achieved regardless of the order and with or without overlap of the pump and the Stokes sub-pulses of the trains. Generalized STIRAP schemes of population transfer in N-level system with sequential couplings are also examined. The mechanism of the population transfer and the robustness of the proposed schemes are discussed.

TL;DR: In this paper , the authors show how to implement faster high fidelity two-qubit gates on neutral atoms through the dipole blockade mechanism by exciting the qubits with the same pulses after optimizing both temporal and spatial parameters.
