We study the problem of quantum state exchange between two coupled modes of the electromagnetic field modelled by quantum oscillators. Analysing the structure of propagators of the Schrödinger equation with the most general weak bilinear resonance coupling, we find the conditions of the exchange in both `narrow' and `wide' senses.
