基于一维双阱超晶格,每个位置单位填充超冷原子,我们提出了一种通过共振晶格振动在超晶格中产生可扩展纠缠态的方案。我们的方案利用周期晶格调制使每个单元格中的两个原子在轨道自由度方面纠缠,并且超晶格中的完整原子系统成为一个二部纠缠原子对的簇。为了证明这一点,我们使用玻色子的多层多构型时间相关哈特里方法进行了量子动力学模拟,该方法考虑了原子之间的所有相关性。提出的二部纠缠簇是各种量子应用的重要资源,例如基于测量的量子计算。该方案具有可扩展性高、处理速度快、对目标纠缠态具有丰富的可控性和现有实验技术可及性等优点。
Based on a one-dimensional double-well superlattice with a unit filling of ultracold atoms per site, we propose a scheme to generate scalable entangled states in the superlattice through resonant lattice shakings. Our scheme utilizes periodic lattice modulations to entangle two atoms in each unit cell with respect to their orbital degree of freedom, and the complete atomic system in the superlattice becomes a cluster of bipartite entangled atom pairs. To demonstrate this we perform $ab \ initio$ quantum dynamical simulations using the Multi-Layer Multi-Configuration Time-Dependent Hartree Method for Bosons, which accounts for all correlations among the atoms. The proposed clusters of bipartite entanglements manifest as an essential resource for various quantum applications, such as measurement based quantum computation. The lattice shaking scheme to generate this cluster possesses advantages such as a high scalability, fast processing speed, rich controllability on the target entangled states, and accessibility with current experimental techniques.
