| 摘 要： | 通过单原子拉曼跃迁,提出了自旋为1的玻色-爱因斯坦凝聚体中多粒子的最大纠缠态的理论处理方法.并且,发现文献1]所提出的3-模模型,经过一个简单的方法可以简化成有效的2-模模型.另外,在这个系统中,文中还提出了一种产生原子-原子间连续变量纠缠态的方案.

| Abstract: | A theoretical treatment of the proposa for creating maximally entangled sates of many particles in spin-1 Bsoe-Einstein condensates(BECs) is presented by applying a single atom Raman transition.It is shown that the three-mode model suggested in reference 1] can be further reduced to an effective two-mode one by a simple method.It also suggests a scheme for generating the atom-atom continuous-variable entangled states in this system. |
