- Abstract summary: We show that a two-color excitation with a combination of two off-resonant pulses making use of the Swing-UP of quantum EmitteR population mechanism is able to invert the system.
We extend our considerations to the three-level system, where a strong mixing between the bare states takes place.

- Abstract: To coherently control a few-level quantum emitter, typically pulses with an
energy resonant to the transition energy are applied making use of the Rabi
mechanism, while a single off-resonant pulse does not result in a population
inversion. Surprisingly, a two-color excitation with a combination of two
off-resonant pulses making use of the Swing-UP of quantum EmitteR population
(SUPER) mechanism is able to invert the system. In this paper, we provide an
in-depth analysis of the SUPER scheme within the dressed-state picture. We show
that the SUPER mechanism can be understood as a driving of the transition
between the dressed states. In the two-level system this allows us to derive
analytic expressions for the pulse parameters yielding a population inversion.
We extend our considerations to the three-level system, where a strong mixing
between the bare states takes place. The insights gained from these results
help in finding accessible regimes for further experimental realizations of the
SUPER scheme and similar two-color excitation schemes.

emitters via two-photon excitation [49.1574468325115]
Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement.
We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.
