    "abstract": "We discuss the problem of the information transfer (exchange of states\nconfiguration) between two interacting quantum systems along their evolution in\ntime. We consider the specific case of two modes of the electromagnetic field\nwith rotating wave coupling interaction (up-conversion in a nonlinear crystal).\nWe verify that for certain initial states of the fields the swapping of state\nconfiguration occurs with conservation of the mean energy of each mode (without\nenergy transfer), characterising thus pure information flow.",
