Query: Photon Number Splitting of Squeezed Light by a Single Qubit in Circuit
  QED   We theoretically propose an efficient way to generate and detect squeezed
light by a single qubit in circuit QED. By tuning the qubit energy splitting
close to the fundamental frequency of the first harmonic mode (FHM) in a
transmission line resonator and placing the qubit at the nodal point of the
third harmonic mode, one can generate the resonantly enhanced squeezing of the
FHM upon pumping with the second harmonic mode. In order to investigate the
photon number splitting for the squeezed FHM, we have numerically calculated
the qubit absorption spectrum, which exhibits regularly spaced peaks at
frequencies separated by twice the effective dispersive shift. It is also shown
that adding a small pump field for the FHM makes additional peaks develop in
between the dominant ones as well.
