Optimally driving multi-photon transitions in the perturbative single-mode regime

Quantum Physics 2026-01-12 v1

Abstract

The rate of mm-photon transitions in matter, induced by an incident light field, depends on the field's mmth order coherence function. Consequently, the coherence properties of the light field may be shaped to increase the rate of multi-photon transitions. Here, we determine the optimal state of a weak fixed-intensity, narrow-band incident light field, with a restricted maximal photon number, that optimally drives mm-photon transitions in the case of a short-lived atomic multilevel system. We show that, in this case, no quantum properties of the light field need to be exploited, but that classical mixtures of coherent states are optimal.
