  Electromagnetic radiation is known to be associated with certain
gravitational waves events, i.e. the collision of binary neutron stars.
Establishing this connection is non-trivial. However, if electromagnetic
counterparts could be produced by directly converting gravitons into photons,
then a simple smoking gun test exists linking the two events. This model uses
the general and conversion mechanism discussed by Raffelt and Stodolsky.
Furthermore, because this mechanism is generic to the symmetries of general
relativity and the standard model and because it assumes a quantised
gravitational field, we may probe both the existence of the graviton and the
scale at which quantum gravity effects (and thus very high-energy phenomena)
become relevant using simple low-energy experiments.
