Query: Transparency and amplification in a hybrid system of mechanical
  resonator and circuit QED   We theoretically study the transparency and amplification of a weak probe
field applied to the cavity in hy- brid systems formed by a driven
superconducting circuit QED system and a mechanical resonator, or a driven
optomechanical system and a superconducting qubit. We find that both the
mechanical resonator and the su- perconducting qubit can result in the
transparency to a weak probe field in such hybrid systems when a strong driving
field is applied to the cavity. We also find that the weak probe field can be
amplified in some parameter regimes. We further study the statistical
properties of the output field via the degrees of second-order coherence. We
find that the nonclassicality of the output field strongly depends on the
system parameters. Our studies show that one can control single-photon
transmission in the optomechanical system via a tunable artificial atom or in
the circuit QED system via a mechanical resonator.
