Abstract
(1) A technique for the preparation of Fock states of a harmonic oscillator strongly coupled to a single two-level atomic transition is proposed due to the observation of quantum jumps. Examples are taken from the fields of ion trapping and cavity QED, where number states of he quantized atomic motion and photon number states may be prepared respectively. (2) We discuss a scheme for preparing coherent squeezed states of motion in an ion trap based on the multichromatic excitation of a trapped ion by standing- and traveling-wave light fields. The squeezed state is produced when the beat frequency between two standing-wave light fields is equal to twice the trap frequency, and is indicated by a {open_quotes}dark resonance{close_quotes} in the fluorescence emitted by the ion.
