Query: Control of electron-hole pair generation by biharmonic voltage drive of
  a quantum point contact   A time-dependent electromagnetic field creates electron-hole excitations in a
Fermi sea at low temperature. We show that the electron-hole pairs can be
generated in a controlled way using harmonic and biharmonic time-dependent
voltages applied to a quantum contact and obtain the probabilities of the pair
creations. For a biharmonic voltage drive, we find that the probability of a
pair creation decreases in the presence of an in-phase second harmonic. This
accounts for the suppression of the excess noise observed experimentally
[Gabelli and Reulet, arXiv:1205.3638] proving that dynamic control and
detection of elementary excitations in quantum conductors are within the reach
of the present technology.
