Deterministic preparation of nonclassical states of light in cavity optomechanics

Cavity-optomechanics is an ideal platform for the generation non-Gaussian quantum states due to anharmonic interaction between light field and mechanical oscillator; but exactly this also impedes preparation in pure of field. In paper we derive a driving protocol that helps exploit state preparation, ensures remains close-to-pure. This shall enable deterministic photon Fock or coherent superpositions thereof.
