Abstract

A new method to prepare dark squeezed states of the motion of a trapped ion that interacts with a standing wave light field has been proposed.This method is based on modulation of the phase of the standing wave field.The dependence of the squeezed amplitude on the modulation amplitude is investigated.Choosing the appropriate modulating amplitude,we can produce the best squeezed vibrational state of the ion and find that its generation is companied by cancellation of the emitted fluorescence.In addition,an experiment configuration about its preparation is proposed and discussed.

‘‘Dark’’ squeezed states of the motion of a trapped ion

J. I. Cirac, A. S. Parkins, R. Blatt +1 more

We propose 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 ``dark resonance'' in the fluorescence emitted by the ion.

(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.

Preparation of Squeezed State and Entanglement State Between Vibrational Motion of Trapped Ion and Light

Zhong-Jie Wang

Several schemes have been proposed to prepare two-mode squeezed state and entanglement state between motional states of a single trapped ion and light. Preparation of two-mode squeezed state is based on interaction of a trapped ion located in light cavity with cavity field. Preparation of entanglement state is based on interaction of a trapped ion located in light cavity with cavity field and a traveling wave light field.

Nonclassical properties and generation of excited entangled coherent states of motion of a trapped ion

Zhongjie Wang

We studied the two-mode squeezing of excited entangled coherent states and found that the deeper the two-mode squeezing, the larger the excitation number. In the end, we proposed a new method for preparing two-mode excited entangled coherent states of vibrational motion of a trapped ion by applying the interaction of a single two-mode trapped ion with many traveling wave light fields with different frequencies.
