Query: Kapitza-Dirac blockade: A universal tool for the deterministic
  preparation of non-Gaussian oscillator states   Harmonic oscillators count among the most fundamental quantum systems with
important applications in molecular physics, nanoparticle trapping, and quantum
information processing. Their equidistant energy level spacing is often a
desired feature, but at the same time a challenge if the goal is to
deterministically populate specific eigenstates. Here, we show how interference
in the transition amplitudes in a bichromatic laser field can suppress the
sequential climbing of harmonic oscillator states (Kapitza-Dirac blockade) and
achieve selective excitation of energy eigenstates, Schr\"{o}dinger cats and
other non-Gaussian states. This technique can transform the harmonic oscillator
into a coherent two-level system or be used to build a large-momentum-transfer
beam splitter for matter-waves. To illustrate the universality of the concept,
we discuss feasible experiments that cover many orders of magnitude in mass,
from single electrons over large molecules to dielectric nanoparticles.
