“…angular momentum) states can be thought of as cooling the internal degrees of freedom. Since such cooling is intrinsically connected to cooling motional degrees of freedom in a number of cooling techniques (see, for example, [7][8][9]), the problem we discuss here is of relevance to the general problem of cooling atoms and molecules.…”

Efficient initialization and manipulation of quantum states is important for numerous applications and it usually requires the ability to perform high fidelity and robust swapping of the populations of quantum states. Stimulated Raman adiabatic passage (STIRAP) has been known to perform efficient and robust inversion of the ground states populations of a three-level system. However, its performance is sensitive to the initial state of the system. In this contribution we demonstrate that a slight modification of STIRAP, where we introduce a non-zero single-photon detuning, allows for efficient and robust population swapping for any initial state. The results of our work could be useful for efficient and robust state preparation, dynamical decoupling and design of quantum gates in ground state qubits via two-photon interactions.

“…Previous laser cooling methods developed to improve loading efficiency for MOTs that trap Yb and other alkaline-earth-metal-like atoms include tailored Zeeman slowers [7][8][9] and preloading 2D-MOTs [10]. Other methods include adiabatic rapid passage [11][12][13][14][15][16][17], Sisyphus-like deceleration [18], two-photon cooling [19], two-color cooling [20,21], and quenched narrow-line cooling [22][23][24] that takes advantage of the narrower transitions to achieve very low temperatures. Combining several of these techniques can produce an ultracold atom source with higher phase-space densities [25].…”
