The interaction of a two-level system with a light field is one of the most important models in quantum optics.
In this contribution, we investigate a Jaynes-Cummings model with two non-degenerate, off-resonant, photon modes coupled to a two-level emitter. We find parameters, for which we can identify a multi-photon scattering leading to full inversion of the emitter while transferring off-resonant photons from one mode to the other.
The results can be understood as a quantized analogue of the off-resonant quantum control scheme known as Swing-UP of quantum EmitteR (SUPER). Unlike the SUPER scheme, which requires two off-resonant pulses to be present at all times, our model only needs one mode initially occupied and the other mode available to achieve full emitter inversion.
Our results enable novel schemes of photon control for quantum photonics.
