利用∧型三能级原子与腔场的Raman相互作用制备二项式态的叠加态(英文)

PREPARATION OF SUPERPOSITION STATES OF THE BINOMIAL STATE VIA THE RAMAN INTERACTION OF ∧-TYPE THREE-LEVEL ATOM WITH THE CAVITY-FIELD

提出了一种制备二项式态的叠加态，亦即类Schr6山nger猫态的方案．在这个方案里，A型三能级原子被送入初始时处于二项式态的腔中，通过原子一腔场的Raman相互作用，原子一胜场系统处于缠结态·通过对原子的选择测量，原子一腔场塌缩到类Schrodnger猫态．

A scheme is proposed for the preparation of superpositions of the binomial state, i. e.Schrodinger-cat-like states. In the scheme a ∧-type three-level atom is sent through the cavity filledwith the binomal state. The entanglement of atom-cavity-field state collapses into Schrodinger-cat-Iikestates through atomic selective measurement.
