Abstract

一个计划为经由堕落拉曼相互作用产生一个四光子的协调状态被介绍。计划不需要古典地操作原子。Itsanother 优点是原子自发的排放能被忽视。因此，系统的连贯可以更好被维持。计划能被概括产生 2 ~ n 的重叠 2 ~ n 的协调状态和重叠二模式的协调状态。在每个模式的协调状态相称性地在一个圆上。

Generation of Four-Photon Coherent State via Degenerate Raman Interaction

Chen Mei-Feng

A scheme is presented for generating a four-photon coherent state via the degenerate Raman interaction. The scheme does not need classical fields to manipulate the atoms. Its another advantage is that the atomic spontaneous emission can be neglected. Therefore, the coherence of the system may be better maintained. The scheme can be generalized to generate superposition of 2 n coherent states and superposition of 2 n two-mode coherent states. The coherent states in each mode are on a circle symmetrically.

Generation and detection of two-photon coherent states in degenerate four-wave mixing

Horace P. Yuen, Jeffrey H. Shapiro

It is shown that degenerate four-wave mixing generates two-photon coherent states (TCS) of the radiation field for modes that are proper combinations of the output object and image waves. TCS light has novel quantum behavior, which can be probed by homodyne detection, intensity interferometry, or photocount statistics. Numerical estimates indicate that the generation and detection of TCS light via degenerate four-wave mixing and homodyne detection can be accomplished with current technology.

Generation of Superpositions of Atomic Coherent States Through Raman Atom-Field Interaction

Zheng Shi-Biao

We propose a scheme for the generation of superpositions of collective atomic coherent states. In the scheme a collection of degenerate -type three-level atoms is confined in a high- cavity and interacts with the cavity field in a Raman manner. Then a state reduction on the field collapses the atomic system onto a superposition state.
