%X We
fabricated a hybrid device with two distant graphene double quantum
dots (DQDs) and a microwave resonator. A nonlinear response is observed
in the resonator reflection amplitude when the two DQDs are jointly
tuned to the vicinity of the degeneracy points. This observation can
be well fitted by the Tavis–Cummings (T–C) model which
describes two two-level systems coupling with one photonic field.
Furthermore, the correlation between the DC currents in the two DQDs
is studied. A nonzero cross-current correlation is observed which
has been theoretically predicted to be an important sign of nonlocal
coupling between two distant systems. Our results explore T–C
physics in electronic transport and also contribute to the study of
nonlocal transport and future implementations of remote electronic
entanglement.
