  We theoretically consider wave mixing under the irradiation of a single qubit
by two photon fields. The first signal is a classical monochromatic drive,
while the second one is a nonclassical light. Particularly, we address two
examples of a nonclassical light: (i) a broadband squeezed light and (ii) a
periodically excited quantum superposition of Fock states with 0 and 1 photons.
The mixing of classical and nonclassical photon fields gives rise to side peaks
due to the elastic multiphoton scattering. We show that side peaks structure is
distinct from the situation when two classical fields are mixed. The most
striking feature is that some peaks are absent. The analysis of peak amplitudes
can be used to probe photon statistics in the nonclassical mode.
