摘要:

里德伯原子间的偶极封锁被认为是中性原子量子信息处理的基本工具。在这里,我们证明实验的里德伯封锁的两个单独的原子分开4 $μ$ m。此外,我们发现,在这种制度下,单原子激发增强了集体的两个原子的行为与激发的纠缠态。这一观测结果是利用里德伯偶极相互作用对两个或多个原子纠缠进行确定性操纵的关键一步。

英文摘要:

The dipole blockade between Rydberg atoms has been proposed as a basic tool in quantum information processing with neutral atoms. Here we demonstrate experimentally the Rydberg blockade of two individual atoms separated by 4 $μ$m. Moreover, we show that, in this regime, the single atom excitation is enhanced by a collective two-atom behavior associated with the excitation of an entangled state. This observation is a crucial step towards the deterministic manipulation of entanglement of two or more atoms using the Rydberg dipole interaction.
