We discuss a proposal for the efficient generation of the maximally entangled atomic N-GHZ state in a spinor-1 condensate by driving internal state atomic Raman transitions using (classical) laser fields. We illustrate the dynamics in terms of a quantum Zeno subspace and identify the resultant atomic elastic collision in facilitating the deterministic entanglement creation. Our proposal can be readily implemented in several laboratories where ferromagnetic spinor condensates (of 87Rb atoms) are investigated.
我们讨论了一种通过使用（经典）激光场驱动内态原子拉曼跃迁，在自旋-1凝聚体中高效生成最大纠缠原子N-GHZ态的方案。我们根据量子芝诺子空间来说明动力学，并确定了由此产生的原子弹性碰撞在促进确定性纠缠产生方面的作用。我们的方案可以在几个研究铁磁自旋凝聚体（87Rb原子）的实验室中轻松实现。
