Preparation of Motion Entangled Coherent States of Two Cavity Mirrors

Shi‐Biao Zheng

A scheme is proposed for the generation of entangled coherent states of two spatially separated cavity mirrors. In the scheme, a two-level atom is sent through two cavities, each having a movable mirror, to produce an entangled photon state for the cavity fields. Then the optomechanical effects further entangle the mirror motions with the cavity fields. A second two-level atom, passing through the cavities, is state-selectively measured, which reduces the mirror motions to an entangled coherent state.We also show how to distinguish such an entangled state from a classical mixture.

Realization of Strong Squeezing for a Macroscopic Oscillator

Zheng Shi-Biao

We propose a scheme to realize strong squeezing for the motion of a cavity mirror through atom-field and field-mirror interactions. We also show how to generate superpositions of several coherent states along a line for such a macroscopic oscillator.

Generation of Superpositions of Squeezed Coherent States

Zheng Shi-Biao, Guo Guang-Can

A scheme to prepare superpositions of squeezed coherent states is presented. It involves an appropriately prepared atom crossing a high- Q cavity initially filled with a squeezed coherent field. After the nonresonant interaction with the cavity field the detection of the atomic state leaves the cavity field in a superposition of two squeezed coherent states.

Preparation of nonclassical states in cavities with a moving mirror

Sougato Bose, Kurt A. Jacobs, P. L. Knight

We describe how a quantum system composed of a cavity field interacting with a movable mirror can be utilized to generate a large variety of nonclassical states of both the cavity field and the mirror. First we consider state preparation of the cavity field. The system dynamics will prepare a single mode of the cavity field in a multicomponent Schr\"odinger-cat state, in a similar manner to that in a Kerr medium. In addition, when two or more cavity modes interact with the mirror, they can be prepared in an entangled state, which may be regarded as a multimode generalization of the even and odd coherent states. We show also that near-number states of a single mode may be prepared by performing a measurement of the position of the mirror. Second we consider state preparation of the mirror and show that this macroscopic object may be placed in a Schr\"odinger-cat-like state by a quadrature measurement of the light field. In addition, we examine the effect of the damping of the motion of the mirror on the field states inside the cavity and compare this with the effect of cavity field damping.
