  bibo_abstract:
  - <jats:p>Indefinite causal order (ICO) has the potential to be a new resource for
    quantum information processing. In most of its experiments, ICO has been investigated
    in a photonic platform. Here, we investigate ICO in a cavity quantum electrodynamics
    system composed of two cavities. Our results show that ICO can create highly entangled
    states of two distant cavity fields that never interact directly independent of
    the initial (excited or ground) state of the atom. These entangled states can
    have the form of one- or two-photon NOON states. We show that ICO can interchange
    one photon between both cavities without changing the state of the atom, something
    that is impossible to achieve for two cavities in well-defined order. Furthermore,
    the vacuum Rabi oscillations either disappear or lose their sinusoidal form with
    ICO. Our results show the potential that ICO can offer in the paradigm of light-matter
    interaction for coherently controlling atom-field observables.</jats:p>@eng
